TURCZANINOWIA , vol: 26 , 59-71, 2023 , 10.14258/turczaninowia.26.4.11.

Abstract:

The present review study is an attempt to assemble and scrutinize major taxonomic and floristic works on the family Arecaceae and present revised information both on diversity and geography of the family in India. The study enumerates total 85 native taxa (84 species and one subspecies) belonging to 19 genera of Arecaceae in the country, where the genus Calamus is represented by 35 taxa (34 species and one subspecies), and remaining genera by less than ten species each. The present list of accepted species includes synonyms, data on their distribution, ecology (forest types, elevation) and status in the country. Among these 85 taxa, 21 species are currently considered under five different categories of IUCN, i.e. twelve species are attributed to Least Concern category, five to Vulnerable, three to Near Threatened, and one species to Endangered and Extinct in the Wild respectively. Total eleven species are endemic to India where one species is distributed in Peninsular India, one in Peninsular and Nicobar Islands, one in Kerala, Tamil Nadu, Karnataka and Maharashtra, two in Nicobar Islands, two in Andaman Islands, two in Andaman and Nicobar Islands, and two in Western Ghats. Majority of the species were found to be confined to evergreen and rain forests. The species occur from lowlands to 2400 m elevation. Common cultivated taxa are excluded here.

S. Mehmud, H. Roy

Indonesian Journal of Forestry Research , vol: 10 , 163-168, 2023 , https://ejournal.aptklhi.org/index.php/ijfr/articl

Abstract:

The stem anatomy of the genus Pinanga Blume distributed to Assam of northeast India remains unattended. An anatomical study was conducted to address this research gap, where the plant samples to Pinanga were collected from different parts of Assam and identified as P. gracilis, P. griffithii, and P. sylvestris. The findings recorded anatomical variation among the species. Freehand sections of the stems were conducted, double-stained, quality specimens mounted, and suitable slides were observed under a light microscope. The types of epidermal cells and metaxylem vessels were variable among the studied species. In this study, vascular bundles with more than one metaxylem vessel were also recorded, which can be used for identification.

SELAGINELLA OPACA (Selaginellaceae): NEW DISTRIBUTION RECORD FOR NORTH EASTERN REGION, INDIA.

K Aran, H Roy

JOURNAL OF ECONOMIC AND TAXONOMIC BOTANY , vol: 46 , 139-142, 2022

Abstract:

Selaginella P. Beauv.(Selaginellaceae) is a wellknown genus of Spike mosses (Setyawan, 2014) occurring throughout the world, with about 800 species (Zhou & Zhang, 2015). Dixit (1992) listed 21 species of Selaginella from Arunachal Pradesh, India. Fraser-Jenkins et al.(2016) reported four new additions to the state but doubtful two species of Dixit’s list, and considered one as misidentification and another as a synonym. Soni et al.(2021) reported 24 species of Selaginella from the State. During the study of Selaginellaceae of Arunachal Pradesh, an interesting species of Selaginella was collected from Roing, Lower Dibang Valley and Kheti village of Tirap district. It does not agree with any of the species of Selaginella so far reported from the State (Soni et al., 2021) and it was identified as Selainella opaca Warb. which constitutes a new record for North Eastern Region (NER), India. A detailed first hand description of the species is provided with two photo-plates, portraying its diagnostic traits under light microscope and as Scanning Electron Microscopic (SEM) images of the spores for its proper identification.

Selaginella miniatospora (Dalz.) Bak.(Selaginellaceae)-a new record for Northeast India

H Roy, SK Borthakur

Asian Journal of Conservation Biology , vol: 2 , 79-81, 2013

Abstract:

Northeastern region is at the conjunction of the Eastern Himalayan and Indo-Burma biodiversity hotspots which is regarded as a major center of biodiversity and one of the hotspots of Pteridophyte diversity. The region also a meeting place of flora of the Himalayas and Peninsular India and represents the transition zone of the Indian, Indo-Malayan and Indo-Chinese biogeographic regions. Assam is one of the eight states of Northeastern India with rich pteridophytic flora which has distinctiveness on account of their species diversity and peculiar formations (Bir et al., 1989). In spite of this, fern-allies of the state have not been studied in detail so far, except a few sporadic works (Alston, 1945; Barua et al., 1989; Bhattcharya et al. 1995; Bir et al., 1992; Dixit 1992; Dutta et al., 1980; Handique and Konger 1986; Islam 1983; Nath and Bhattacharya, 2002; Panigrahi, 1960; Thakur 1962). During the course of on going studies on Fern-allies of Assam, the authors collected some specimens of Sellaginella Beauve from Nagaon and Kamrup districts of the state and later identified as Selaginella miniatospora (Dalz.) Bak. Careful scrutiny of relevant literatures (Alston, 1945; Baishya and Rao, 1982; Barua et al., 1989; Bhattcharya et al., 1995; Bhattcharya et al., 1998; Bir, 1976, 1987, 1993; Bir et al., 1992, 1989; Borthakur et al., 2001; Dixit, 1984, 1992; Dixit and Vohra, 1984; Dutta et al., 1980; Fraser-Jenkins, 2008; Handique and Konger, 1986; Islam, 1983; Jain, 1991; Kachroo et al., 1989; Kaur and Chandra, 1994; Manickam and Irudayaraj, 1992; Mukhopadhyay, 2001; Nath and Bhattacharya, 2002; Panigrahi, 1960; Panigrahi and Choudhury, 1962; Panigrahi

S.K. Begum, S.S., Roy, H., Nath, M. & Borthakur

Pleione , vol: 5 , 2011

Abstract:

The complex phytogeography is correlated with the wide range of altitude, the meridional orientation of the mountains and the geological past of the land (Rao 1974). Phytogeography deals with the distribution of plants in present and past (Good 1974). According to Good (1974) India, along with the continental South-East Asian region falls under the paleotropical kingdom and Indo-Malaysian subkingdom. On the basis of distribution of flora, the Indian Subcontinent has been subdivided into various botanical or floristic provinces by Clarke (1898); Hooker (1906); Chatterjee (1939); Meher-Homji & Mishra (1971) and Rao (1974). On the basis of climatic and geographical conditions the earth is generally divided into broad vegetational belts and accordingly India is under Tropical belt. Meher-Homji (1972) recognized 25 floristic provinces in India. The present study area, Nameri National Park (NNP) is under the province of Assam.‘Because of its distinctive flora’, Assam has been treated as a distinct phytogeographical area (Chatterjee 1939; Clarke 1898; Hooker 1906; Sahni 1981), which forms an integral part of north-easterly extension of the Eastern Himalaya. Phytogeography can also be studied in the context of the historical geomorphology of a region. Ancient Gondwana land and the Great Ice Age both have influenced the formation of the present day flora of the region. Being a part of the Gondwana land, the flora shows relationship with that of Malaysia and Peninsular India and to some extent with that of African elements (Rao 1974). The influx of humid tropical Asiatic elements has taken place through the Assam gateway. The tropical Asiatic …

Winter foraging ecology of stump-tailed macaques Macaca arctoides in the Hollongapar Gibbon Sanctuary, Assam, India

Stotrabhashyam, S., Sharma, N., Kumar, A and Sinha A

Journal of Biosciences , vol: 48 , 2023 , https://doi.org/10.1007/s12038-023-00356-0

Abstract:

Frugivorous primates in temperate and subtropical regions often experience a shortage or complete absence of fruits for several months of the year. We studied the foraging ecology of a group of stump-tailed macaques Macaca arctoides in a subtropical forest during winter, when fruit abundance was low. We conducted this study in the Hollongapar Gibbon Sanctuary, Assam, India, from December 2015 to April 2016. We estimated the time–activity budgets, diet, and habitat use of the study troop and also conducted vegetation sampling and phenological monitoring of the study area. The stump-tailed macaque troop spent about 73.2% of its time foraging and feeding, with seasonal differences in food species intake and in habitat use. Open degraded forests were primarily used in December, January, and February, when the macaques largely fed on shoots of the bamboo Schizostachyum polymorphum and roots of the herb Forrestia (= Amischotolype) mollissima, while they mostly utilised F. mollissima in canopy-covered, degraded forests in March and April. There was a major shift from a primary diet of fruits in the wet season, reported from earlier studies, to possibly relatively poor-quality, but abundant, shoots and roots in winter. This suggests that the consumption of these poor-quality fallback food species is a key dietary adaptation of the macaques to periods of fruit scarcity. Although our preliminary study suggests that the feeding behaviour of the stump-tailed macaque in its subtropical semi-evergreen forest habitat appears to be similar to that of its congeneric species in temperate forests, further investigations are needed to firmly establish the observed foraging patterns of this vulnerable cercopithecine species in its last lowland rainforest refuge in northeastern India.

Abstract:

Phenology is the study of recurrent biological events of animals and plants. In this article, we trace the history of phenological studies, understand the factors that drive phenology, discuss various ways one can observe phenological events, and how these observations are important and cost-effective ways to detect signatures of climate change. Finally, we discuss how using the latest technology, we can contribute to furthering phenological studies.

Past shadows and gender roles: Human elephant relations and conservation in Southern India

Journal of Political Ecology , vol: 31 , 604-623, 2024 , https://doi.org/10.2458/jpe.2834

Abstract:

Some conceptual thinking about human-wildlife relations has lacked translations into empirical studies with an in-depth enquiry into social, cultural, economic and ecological aspects. This study explores human-elephant relations in a cohabited landscape in the Western Ghats of India, with a focus on 'more than conflict' relations. The Valparai plateau, in the Indian Western Ghats, is a landscape dominated by tea estates and remnants of rainforest fragments where human communities cohabit and closely interact with wildlife. We offer an empirical contribution on the variegated and paradoxical relation between care and fear, between empathy and hate and between the residents and elephants of Valparai. Where conflicts occur between elephants and humans, they have multiple meanings. Gender and unpleasant memories serve as drivers of negative attitudes towards wildlife. A conservation intervention based on engagement and collaboration with local people was perceived as highly effective. Preventive and mitigative, rather than reactive conflict mitigation strategies may have a significant role to play in maintaining the social carrying capacity of local communities towards elephants. We explore the many facets of human-elephant relations, and the numerous entanglements between them, thereby adding multiple layers to the extant knowledge of human-animal relations in the Western Ghats.

When the Jungles Turned to Forest: Habitat Loss and Fragmentation as Drivers of Biodiversity Loss in the Lowland Tropical Forests of the Upper Brahmaputra Valley

Gogoi, N, Sengupta S and Sharma N

GUINEIS Journal: An Interdisciplinary peer-reviewed Journal of North East India Studies , vol: XI , 76-92, 2023

Abstract:

Deforestation, accompanied by habitat loss, fragmentation and degradation, is the major challenge to biodiversity conservation, affecting nearly all global ecosystems. Tropical forests, in particular, have faced unprecedented loss, with a quarter of their land cover lost by the end of the 20th century. North East India’s landscape is dotted by remnant fragments of previously contiguous tropical and sub- tropical forests. The forested fragments of the Upper Brahmaputra Valley of Assam, composed of lowland tropical forests, which have existed for nearly a hundred years, provide the backdrop for a comprehensive investigation into the complex ecological processes at work in these isolated and biodiversity-rich habitats. By collating and discussing studies on historical deforestation, urbanisation, monoculture plantations, current impacts on species extinction and environmental policies from this region, this review aims to provide a broad overview of the complex dynamics and distinct patterns shaping the ecological landscape of Assam.

Abstract:

Arunachal Himalayas lost 110 glaciers in 32 years as a result of climate change. The study indicates that in 1988, there were 756 glaciers covering an area of 585.23 (±3.4) sqkm. By 2020, this number had decreased to 646 glaciers, with a corresponding reduction in the area to 275.381 (±2.9) sqkm. The overall rate of change is observed to be 16.94 sqkm/year.

This has serious implications for freshwater distribution in downstream regions, regional climate regulation, climate change-induced disasters such as GLOF, the overall cryosphere ecosystem, and the dependent population.Arunachal Himalayas lost 110 glaciers in 32 years

Abstract

An integrated treatment coupling alkali, steam explosion and ammonia/chlorine-free bleaching with sequential mild acid pretreatment were performed to isolate and characterize cellulose from banana agrowastes followed by optimized enzymatic hydrolysis to glucose. The cellulose yield, compositional, microstructural, and morphological analysis initially obtained from three post-harvest banana agrowastes (peel, pseudostem, and peduncle) were surveyed. Isolation parameters for banana peduncle agrowastes, the most efficient precursor, were reconfigured for acid hydrolysis by applying an orthogonal L₉ array of Taguchi design. Effects of solution-to-pulp ratio, acid concentration, temperature, and reaction time on physicochemical parameters were assessed resulting in ~81% cellulose recovery. Subsequently, cellulase driven enzymatic conversion to glucose was modelled using response surface methodology (RSM), where the mutual influences of incubation time, enzyme concentration, substrate concentration, and surfactant concentration were investigated. Artificial Neural Network (ANN) modelling further improved upon RSM optimizations ensuing ~ 97% optimized glucose yield, verified experimentally.

Abstract:

Restriction–modification (R-M) systems form a large superfamily constituting bacterial innate immunity mechanism. The restriction endonucleases (REases) are very diverse in subunit structure, DNA recognition, co-factor requirement, and mechanism of action. Among the different catalytic motifs, HNH active sites containing REases are the second largest group distinguished by the presence of the ββα-metal finger fold. KpnI is the first member of the HNH-family REases whose homologs are present in many bacteria of Enterobacteriaceae having varied degrees of sequence similarity between them. Considering that the homologs with a high similarity may have retained KpnI-like properties, while those with a low similarity could be different, we have characterized a distant KpnI homolog present in a pathogenic Klebsiella pneumoniae NTUH K2044. A comparison of the properties of KpnI and KpnK revealed that despite their similarity and the HNH motif, these two enzymes have different properties viz oligomerization, cleavage pattern, metal ion requirement, recognition sequence, and sequence specificity. Unlike KpnI, KpnK is a monomer in solution, nicks double-stranded DNA, recognizes degenerate
sequence, and catalyses the degradation of DNA into smaller products after the initial cleavage at preferred sites. Due to several distinctive properties, it can be classified as a variant of the Type IIS enzyme having nicking endonuclease activity.

Abstract:

We demonstrate the remarkable ability of surfaceenhanced Raman spectroscopy (SERS) to track the allosteric changes in restriction endonuclease KpnI (R.KpnI) caused by metal ions. R.KpnI binds and promiscuously cleaves DNA upon activation by Mg2+ ions. However, the divalent ion Ca2+ induces high fidelity cleavage, which can be overcome by higher concentrations of Mg2+ ions. In the absence of any 3D crystal structure, for the first time, we have elucidated the structural underpinnings of such a differential effect of divalent ions on the endonuclease activity. A combined SERS and molecular dynamics (MD) approach showed that Ca2+ ion activates an enzymatic switch in the active site, which is responsible for the high fidelity activity of the enzyme. Thus, SERS in combination with MD simulations provides a powerful tool for probing the link between the structure and activity of enzyme molecules that play vital roles in DNA transactions.

Abstract:

Abstract

Seribiodiversity refers to the variability in silk producing insects and their host plants. The North – Eastern region of India is considered as the ideal home for a number of sericigenous insects. However, no detailed information is available on seribiodiversity of Assam. In the recent times, many important genetic resources are facing threats due to forest destruction and little importance on their management. Therefore, the present study was carried out in different regions of the state during the year 2012-2013 covering all the seasons. A total of 12 species belonging to 8 genera and 2 families were recorded during the survey. The paper also provides knowledge on taxonomy, biology and economic parameters of the sericigenous insects in Assam. Such knowledge is important for the in situ and ex- situ conservation program as well as for sustainable socio economic development and employment generation.

Dr. Tarali Kalita

International Journal of Advanced Research , 2015

Abstract:

Assam and North East India hold an unique position in the global sericulture map for its monopoly in muga culture. The muga silk is the 2nd most expensive silk in the world which is produced by the insect Antheraea assamensis of order Lepidoptera and family Saturniidae. At the present day world, phenotypic variation have been used extensively to describe the population structure in many species and is considered that it plays an important role in conservation strategies of many threatened organisms. In the present study, survey, collection and morphological characterization showed that there exist great variation in color, size and weight of various stages of life cycle of A. assamensis which indicates a higher genetic diversity among the population. Such studies may help to select a beneficial trait for future breeding program and to conduct ex-situ conservation program of the collected population in a conductive climatic condition to prevent the loss of crop failure due to adverse climatic condition.

Characterization of silk fibre in various population of Antheræa assamensis Helfer

Dr. Tarali Kalita

Biodiverse , 2018

Abstract:

OBJECTIVES
• To collect the cocoon sample of Antheraea assamensis from different regions of north east India.
• To study the morphological structure of silk fibre of different population of Antheraea assamensis
• To study the mechanical strength of different population of Anthearea assamensis.

RESULTS AND DISCUSSIONS
The result showed that from the eleven collected population, the silk fibre of wild stocks have more tensile strength than the cultivated stocks. The resultant more tenacity may be due to
higher concentration of alanine and glycine in the wild stocks (Nadiger and Hallyal, 1984) But, due to higher deposition of calcium oxalate crystals the wild cocoons were hard and difficult to real. Ranking of the different population of A. Assamensis on the basis of FTIR ratio revealed that cocoons with lower degree of FTIR value indicates lower degree of mineralization and thereby forming soft cocoons. It is reported that the demineralizing agent such as Ethylendiamine-tetra acetic acid (EDTA), citric acid etc. Can be used to remove calcium oxalate by dissolving the cocoons directly into the solution (Gheysens et al., 2011). The wild stocks and some of the cultivated stocks showed tight packaging of silk fibre indicating better volume of silk fibre.

Journal of Advanced Zoology , 2018

Abstract:

ABSTRACT:

Antheraea assamensis, the producer of golden muga silk is endemic to North East India and
Brahmaputra Valley of Assam particularly. The insect represents phenotypic variabity in different stages of the life cycle. In the present study, eleven populations of muga silk worm are collected from different regions of North east India to assess the DNA polymorphism and genetic distance among the muga silkworm stocks. The extracted genomic DNA were analysed using twenty two Inter Sequence Simple Repeats (ISSR) markers of which ten primers produced 81 bands and 58 bands of them are polymorphic indicating the average percentage of DNA polymorphism 71.60%. The Jaccard similarity coefficient ranged between0.133 to 0.700 indicating high level of gentic diversity. Cluster analysis using Unweighted Pair Group Method (UPGMA) based on ISSR profile divided the eleven accessions into nine clusters. Thus, the study suggested that the population with low genetic variation are homogenous in nature whereas the high genetic variation among the population indicates that those populations have already differentiated into separate gene pool. Therefore, it is important to conserve this separate gene pool without any
inter mixing.

Haematological changes and histopathological alterations in liver and kidney induced by sinarest acute and sub- acute toxicity

Barsha Kalita, Diksha Dutta, Tarali Kalita

Journal of Advanced Zoology , 2019

Abstract:

ABSTRACT:

Sinarest syrup (0.08ml/30g BW) was orally given to swiss Albino mice (C3H/J strain) with the help of oral gavage for 14 days and 28 days. Significant decrease in weight of liver and kidney was recorded and 28 days treated mice liver showed lobule formation. The total number of red blood cells, Haemoglobin %, mean corpuscular volume and packed cell volume significantly decreased (P<0.05). Also, there was a significant increase in number of white blood cells. The serum liver enzymes (SGOT/AST, SGPT/ALT & ALP) showed significant increase indicating
destruction of hepatic cells. The serum creatinine level also significantly increased compared to the control group. The examination of Haematoxylin-Eosin stained liver sections showed focal hepatocyte necrosis, dilated central vein with infiltration of lymphocytes and hematopoietic cells around it, cytoplasmic vacuolations, pyknosis, karyolysis and karyyohexis of hepatic cells and Kupffer cell hyperplasia in the treated group. The histological changes observed in kidney include flattening of the renal tubular cells with loss of brush border, deformed and degenerated glomeruli, vacuolation and completely distorted distal tubules. Therefore, it is advised that caution should be taken with the rampant use of this drug. One should always take this drug in a recommended dose and recommended period only when prescribed by qualified medical practitioners.

Characterisation of cocoon of different population of Antherae aassamensis (Lepidoptera:Saturniidae).

Tarali Kalita and Karabi Dutta

Oriental Insects , 2020 , https://doi.org/10.1080/00305316.2020.1727376

Abstract:

The characterisation of cocoons is one of the most important requirements to know the economic importance of a sericigenous insect. Antheraea assamensis produces the golden muga silk, which is considered as the second most expensive silk in the world for its high quality. Although muga silk worm is a single species, it has many varieties with respect to its geographical areas. However, literary works on the most important economic traits connected to silk production of
different populations of A. assamensis are very limited. Therefore, the present study has been aimed to know the cocoon efficiency and the silk quality of the different populations of the A. assamensis following the standard techniques. The study was performed after collecting the cocoon samples from 11 different regions of the North East India. The result showed that A. assamensis exhibit variation in cocoon colour along with other significant differences in the cocoon weight, shell weight, shell ratio and silk quality. The cocoons of the wild population recorded more cocoon weight, shell ratio, filament length and tenacity but at the same time due to the deposition of higher degree of calcium oxalate crystals on the cocoon surface, they were hard to reel. Based on these characters, the study recommended some stocks, which could be
used for future breeding programme based on the genetic distance between the parents.

Diversity of edible insects in a Natural World Heritage Site of India: entomophagy attitudes and implications for food security in the region

Arup Kumar Hazarika, Unmilan Kalita, Subhash Khanna, Tarali Kalita and Sangeeta Choudhury

Peer J , 2020 , DOI 10.7717/peerj.10248

Abstract:

Insects not only play a significant role in the ecological process of nature but since pre-historic times have also formed a part of the human diet. With a still growing population and skewed demographic structures across most societies of the world, their role as nutrient-rich food has been increasingly advocated by researchers and policymakers globally. In this study, we examine the edible insect diversity and entomophagy attitudes of ethnic people in Manas National Park, a UNESCO Natural World Heritage Site, located in Assam (India). The study involved a field investigation through which the pattern of entomophagy and the attitude towards insect-eating was studied. Following this, we examined the edible insect diversity and abundance at different sampling points. A total of 22 species of edible insects belonging to fifteen families and eight orders were recorded from different habitat types. Out of these 22 species, Orthopterans showed
a maximum number of eight species followed by Hymenoptera (four), Hemiptera (three), Lepidoptera (two), Blattodea (two) and one species each from Coleoptera, Odonata, and Mantodea. Dominance, diversity, and equitability indices were computed along with the relative abundance of the insects concerning four habitat types. Aspects of the economic significance of entomophagy were also observed during the field investigation. To manage insects in the interest of food security, more attention should be given to sustainable collecting and rearing methods emphasizing their economic, nutritional, and ecological advantages.

Current Research in Food Science and Nutrition , 2021 , DOI : https://dx.doi.org/10.12944/CRNFSJ.9.2.31

Abstract:

Rice, the mostly used cereal grain, is composed of three layers-husk, bran and endosperm, each contains various specific components. These layers can be lost or retained depending on the different processing methods used. The objective of the present study was to know the nutritional value of raw and parboiled Ranjit rice obtained by de-husking method using both modern milling and a traditional de-husking method by “Dhenki”. After preparing the rice flour, estimation of carbohydrate, protein, crude lipid, crude fiber, Minerals: Fe, Zn, Ca, vitamins thiamin and niacin were carried out for all the rice samples following standard methods. The milled rice grains showed greater losses in the fat, protein and fiber contents compared to the rice grains de-husked by Dhenki. On the other hand, the parboiling of the paddy prior to de-husking enhanced the nutritional quality of the rice compared to the un parboiled raw rice as parboiling - allows some nutrients like Iron and vitamins to transfer from the hull into the grain. Parboiled rice also showed less carbohydrate content compared to the raw rice. Further study with animal model revealed that parboiled rice de husked by Dhenki showed slow rate of digestion indicating it as a source of good carbohydrate.The findings may be useful in helping the people to choose the right processing methods for rice to obtain maximum yield in nutrition.

Morphological study, nutritional value and phytochemical estimation of four indigenous rice (Oryza sativa L.) varieties of Assam, India

Tarali Kalita and Jimpi Hazarika

Food Research , 2022 , https://doi.org/10.26656/fr.2017.6(1).080

Abstract:

India is a major producer and consumer of rice. Assam is one of the top rice-producing states of the country and is situated in the indo-Burma hotspot, it is gifted with exceptionally rich rice diversity. These indigenous rice varieties have unique properties and are cultivated by the local farmers and are only used for the preparation of traditional cousins. In the present study, four indigenous rice varieties namely Kumol saaul, Kola Bora, Kola kunkuni Joha and Khamti Lahi have been selected for nutritional profiling and bioactive compounds screening. The biochemical estimation of the nutrients was carried out following the guidelines of the Association of Analytical Chemists International. For phytochemical screening, the methanolic extract of the rice samples was prepared and qualitative as well quantitative tests were performed following standard protocols. The carbohydrate content was higher in Kumol saaul (48.3±0.34) and khamti Lahi (38.64±0.4) and therefore may be used to prepare breakfast for the farmers while working in the paddy field and to prepare traditional cousin Tupula vat respectively. The protein content was highest in Kola bora (8.9±0.02) which are used for the preparation of traditional food. Crude lipid, Crude fiber, vitamin and Mineral content also showed significant differences in the four rice varieties. The total anthocyanin content and antioxidant activity were found more in Kola Bora (328.26±0.87, 81.45±2.29) and Kola Kunkuni Joha (11.90±0.89, 67.34±1.23). Thus, the study clearly showed that these indigenous rice varieties are not only traditionally important but also a good source of nutrients and bioactive compounds. It is expected that, in-depth knowledge of nutrients and other bioactive compounds in the rice varieties may be beneficial for their promotion in global the market as well as germplasm conservation.

Journal of Insects as Food and Feed, , 2022 , https://doi.org/10.3920/JIFF2021.0141

Abstract:

Insects as food have been consumed all over the world, mostly by ethnic communities, since time immemorial. With the ever-increasing human population causing an imbalance between food production and nutrition, edible insects are gaining importance as an alternative food source. The aim of this paper is to record the region-specific current practices of entomophagy and their implications in food security. The study involved field investigation to find out the pattern of entomophagy among the scheduled tribes of the Bodoland Territorial Region (BTR), Assam. Following this, we made an effort to estimate the diversity of edible insects at different sampling sites in the studied area. Nutritional profiling of some of the edible insects was carried out to know their potential as a measure of food security. A total of 25 edible insects belonging to 9 orders and 18 families were recorded during the study period. Species diversity was recorded highest in forest/backyard forest habitat followed by agricultural field habitat, open field habitat and swampy area habitat in all the four districts in BTR, Assam. During the consumer survey, a total of 4,051 people belonging to four different scheduled tribes, Bodo, Rabha, Garo and Sarania were interviewed and out of them, 3,840 (94.79%) people were found to consume insects as food. The insects are mostly consumed in fried form, followed by smoked, raw, paste, roasted and curry form. The biochemical analysis of nutrient contents of 11 commonly consumed edible insects showed that they are a rich source of protein, vitamins and micronutrients with a reasonable amount of carbohydrates and lipids with higher radical scavenging activity. To manage insects in the context of food security, increased attention should be given to sustainable collection and successful farming of edible insects for the creation of export potential, giving emphasis on the nutritional advantages.

Changes of quality of freshwater murrels after preserving through low fire burnt process

Devajit Basumatari

Proceedings in the Zoological Society of India , vol: 14 , 91-94, 2015

Abstract:

There are several ethnic processes of the preservation of fishes. Burning the whole fish in low intensity of fire is a process of preservation of some freshwater murrels that is being practiced by some of the ethnic communities inhabiting in the north east part of India. Burnt fish loses about 25% moisture and 50% fat, while the protein and ash content are increased after burning.

In the present study, freshwater murrels, Channa gachua, Channa punctatus and Channa striatus are burnt and the changes of quality with reference to organoleptic evaluation, proximate composition and microbial have been determined from fresh, burnt as well as preserved samples of 7 days

A Comparative Study on Total Muscle Protein Content of Different Fish Species in Fresh and Smoked-Dried Condition and to Analyse their Banding Pattern through SDS-PAGE

Dipika Doloi, Devajit Basumatari

International Journal of Lifescience and Pharma Research , vol: 10 , 51-57, 2020

Abstract:

Fish plays an important role in human nutrition. They are known to be a very healthy food item. They are excellent protein sources that also deliver various minerals and vitamins necessary for good health. Due to the high content of polyunsaturated fatty a cid, fish flesh and fish oil are beneficial in reducing the serum cholesterol. In addition to that, the special type of fatty acid, omega -3 polyunsaturated fatty acid, is recognized as an important component to prevent a number of coronary heart diseases. Fish proteins contain all the essential amino acids in the required proportion and hence have a high nutritional value, which contribute to their high biological value. In fresh fi sh muscles, the water content is strongly bound to the proteins and cannot be easily removed even under higher pressure. For the present study, three different fish species, Clarias batrachus (E1), Mystus tengara (E2) and Puntius ticto (E3) were taken to study their protein content and analyze the electrophoretic protein banding pattern for both fresh and smoked dried conditions. Pr otein extract was made from the muscle tissue of the fishes taken. The protein content was measured by Lowry’s method using BSA protein as standard. The optical density was measu red at 660nm. The electrophoretic protein banding patterns were determined using SDS-PAGE gel electrophoresis. The results showed that the total protein concentration of samples for fresh condition E1F, E2F and E3F was found to be 7.15±0.247 mg/ml, 7.20±0.224 mg/ml and 4.98±0.283 mg/ml respectively and for smoked dried condition E1D, E2D and E3D was 8.48±0.273 mg/ml, 8.31±0.222 mg/ml and 5.81±0.335 mg/ml respectively. The SDS-PAGE electrophoresis showed significant increase in the protein bands of three types of smoked dried fish samples when compared to fresh ones. Therefore, the percentage of protein content in selected smoked dried fishes was found more.

A Comparative Study on Total Muscle Protein Content of Anabas testudineus, Labeo gonius, Labeo rohita and Heteropneustes fossilis and analyse their Electrophoretic Banding Pattern using SDS-PAGE

Dipika Doloi, Devajit Basumatari

International Journal of Lifescience and Pharma Research , vol: 10 , 46-50, 2020 , http://dx.doi.org/10.22376/ijpbs/lpr.2020.10.3.L46

Abstract:

India is undergoing nutrition transition and is facing the dual burden of malnutrition, problem of under-nutrition and malnutrition deficiencies. Fish is one such food that can solve the problem. Fresh fish flesh provides an excellent source of protein for human diet, which is relatively of digestibility, biological and growth promoting value for human consumption. The present study is aimed to determine the total muscle protein content of freshly killed fishes belonging to different species (Anabas testudineus [E1], Labeo gonius [E2], Labeo rohita [E3] and Heteropneustes fossilis [E4]) and also to analyze the electrophoretic banding pattern of muscle protein from the above species through SDS - PAGE gel electrophoresis. Electrophoresis can be used to separate and visualize proteins. In SDS -PAGE, proteins are separated based on size. When protein samples are applied to such gels, it is usually necessary to know the protein content or concentration of the sa mple. The total muscle protein estimation was done by Lowry’s method using BSA protein as standard. The optical densit y was measured at 660 nm. The results showed that the total protein concentration of sample E1, E2, E3 and E4 was found to be 8.31±0.314 mg/ml, 7.65±0.333 mg/ml, 6.98±0.315 mg/ml and 8.98±0.483 mg/ml respectively. The SDS-PAGE electrophoresis done in case of different fish species showed variation in the banding patterns, in which E1 and E4 showed maximum number of bands as compared to E2 and E3. Fishes belonging to the gro up of catfishes and perches were found to contain more amount of protein as compared to Indian Major Carps and Minor Carps. Therefore, fishes play a vital role as it is an important and cheaper source of quality animal proteins.

International Journal of Biology, Pharmacy and Allied Sciences (IJBPAS) , vol: 10 , 2021 , https://doi.org/10.31032/IJBPAS/2021/10.10.5663

Abstract:

Fish plays an important role in human nutrition health. It is a valuable source of protein, minerals, vitamins like A, B, D and fatty acids. Singarah (Mystus sp.) belongs to group catfish is found available in the river Brahmaputra and its tributaries is a very popular having highly demand among the consumers. There are many methods available nowadays for the preservation of fishes. There are also some local methods, fully scientific use by the indigenous people of N.E. of India. Burning of fish in low fire is such a local process of preservation. In the study, freshwater catfish, of genus Mystus like Mystustengara, Mystus vittatus, Mystusca vasius are burnt and observation was done on proximate composition and microbial load from fresh and burnt samples.

Aquatic environments, including wetlands, are one of the most threatened ecosystems worldwide. Considering their ecological importance, wetlands are rightly appraised as 'natural kidneys'. In this current study, the city wetlands of Guwahati were viewed for the first time through the angle of lesser-explored bottom dwellers. Guwahati, a rapidly expanding metropolis, is the gateway to northeast India, part of an Indian biodiversity hot-spot region. This case study comprised the bridge between abiotic and biotic factors, thus directing the pave for characterization of wetlands through benthos analysis. The study, covering seasons, viz. winter, premonsoon and monsoon, revealed 15 definite taxa belonging to 10 orders. The dominance of Chironomidae and Culicidae in certain wetlands indicated high tolerance of Dipterans in a wide range of aquatic environments, including polluted water bodies. Similarly, the presence of Trichopterans, only in the wetland located distant from the mainland city, marked that with less anthropogenic impacts. The Shannon indices for benthos were in the range from 0.17 to 0.97. Density was found to have a significant positive correlation with dissolved oxygen (r = 0.567) and a negative correlation with free carbon dioxide (r =-0.377). In contrast to significant site-wise variation in density, there was no significant difference in benthic diversity across the sites and no significant seasonal variation of benthic density and diversity from the statistical point of view.

International Journal of Biology, Pharmacy and Allied Sciences (IJBPAS) , vol: 11 , 2022 , https://doi.org/10.31032/IJBPAS/2022/11.4.6018

Abstract:

The amount of protein in fish is influenced by fat and water content and as a whole all these are influenced by the various environmental conditions. It has been found that post-preservation, there are various changes observed in the fish irrespective of the types or methods of preservation. In the present study, Wallago attu was chosen for amino acid analysis in two conditions-fresh and ice-preserved (for 15 days in 0°C,-4°C,-10°C, and-20°C). The identification and quantification of different amino acids were made from the HPLC characteristics of authentic samples (Sigma). It was observed that preservation in ice leads to loss of amino acid content, with highest losses at-4°C. The reason for this loss is not entirely known.

Uttar Pradesh Journal of Zoology , vol: 45 , 208-213, 2024 , http://dx.doi.org/10.56557/UPJOZ/2024/v45i33893

Abstract:

In the field of entomophagy, the consumption of insects as a sustainable and nutrient-rich food source has gained increasing attention due to its environmental and nutritional benefits. There has been a growing curiosity and interest in the culinary world regarding insects as a source of food. Far from being a passing trend, the exploration of insect-based cuisine has opened up new dimensions in gastronomy. Among the edible insect species, Oecophylla smaragdina, known as the weaver ant, has emerged as a subject of fascination for its unique cultural significance, ecological relevance, and potential as a nutritional powerhouse. It is consumed by certain tribes of Assam during the primary spring festival in Assam. The study was done to determine the proximate analysis of Oecophylla smaragdina using standard methods. From the study, crude protein content was found to be highest amongst the proximate composition. Thus, this study provides valuable insights about the proximate composition of this insect. Moreover, it also adds another layer of importance as it is consumed during the primary spring festival in Assam, adding cultural significance to it.

Comparative proximate and mineral analysis of fresh and sun-dried fish species with special reference to Puntius sophore (Hamilton, 1822), Gudusia chapra (Hamilton, 1822)

Abstract:

Fishes are consumed as one of the main sources of dietary animal protein. However, fishes are highly perishable and hence different post-harvest methods such as sun-drying are employed to preserve fish for a longer duration of time. Presently sun-dried fishes also have a significant nutritional role in addition to fresh fish. The present study has been conducted to determine the proximate composition and mineral content of fish species namely, Puntius sophore (Puthi), and Gudusia chapra (Koroti) in fresh and sun-dried conditions. The moisture, crude protein, crude fat, ash and carbohydrate content of the fresh and sun-dried P. sophore and G. chapra revealed significantly higher (p<0.05) moisture content in the fresh fish samples than in sun-dried samples. While, significantly higher (p<0.05) crude protein, crude fat, ash and carbohydrate contents were obtained in the sun-dried samples in comparison to the samples in fresh condition. Amongst the minerals studied Na, K, Fe, and Zn were found to be significantly higher (p<0.05) in the sun-dried samples while Ca and Mg were found to be significantly higher (p<0.05) in the fresh fish samples. The present study aims to elucidate the nutritional benefits of consuming sun-dried fishes together with fresh fishes safeguarding nutritional security across a greater population.

Uttar Pradesh Journal of Zoology , vol: 45 , 266-276, 2024

Abstract:

A study was conducted to evaluate the shelf life and quality of the fish at different duration of low temperature preservation. The fish was subjected to sensory evaluation to assess the shelf life and later biochemical and microbial analysis was carried out at an interval of 24 hours upto 96 hours of storage duration. Results of sensory evaluation showed that the fish had an acceptable value of 8.56±0.23 in fresh condition, which slightly changes to 8.5±0.00, 8.1±0.34, 7.8±0.45 and 7.4±0.23 in 24, 48, 72 and 96 hours of storage respectively. Total volatile basic nitrogen (TVBN) analysis showed an increase level from 4.32±0.05 in fresh to 4.34±0.02 with increase in storage duration upto 96 hours without any significant change. The vitamin analysis showed a decreasing trend for storage samples. Among all the fat soluble vitamins, fresh sample showed the highest value for vitamin A which is 62.41±0.5 and lowest value 1.16±0.06 was found for vitamin E. Vitamins showed significant decrease in content during storage. The microbial analysis for Total Plate Count (TPC) increased gradually from 2.38±0.22 in fresh to 2.90±0.51 in 96 hours of storage duration without showing any significant difference. However both Escherichia coli (EC) and Coliform Count (CC) were found absent in both fresh and storage samples. The results of the study showed that, the sensory characteristics, TVBN and microbial count of the fish remains significantly unchanged upto 96 hours of storage. However, results of vitamins showed that Vitamin A and D significantly changed at the end of storage duration while vitamin E and K remain significantly unchanged during the overall storage period. Thus, the biochemical and microbial analysis stated that the preserved fish samples are healthy for human consumption but upto a specific storage period. Overall, it is well recommended to consume fish in fresh condition and for stored fish, not more than 96 hours in the refrigerator in order to preserve the better quality and more benefits for human health.
