Entomophagy practices among the primitive tribes inhabiting the Nilgiris district of Western Ghats, Tamil Nadu, South India Indian Journal of Traditional Knowledge, 2023 Insects have been a traditional food among the people of various countries including India. The Nilgiris district of Western Ghats, Tamil Nadu a recognised biodiversity hotspot in South India, has six different inhabitant primitive tribes namely Todas, Kotas, Kurumbas, Irulas, Paniyas and Kattunayakans , whose insect eating habit and their traditional knowledge on collection, processing and cooking of edible insects have been documented in this study. Eight species of insects viz ., Apis dorsata, Apis cerana, Apis florea , Trigona sp., Oecophylla smaragdina , Vespa affinis and Odontotermes sp. belonging to five families under two orders (Hymenoptera and Isoptera) have been recorded to be used as food. The use value of insects have been calculated and inferred that honey bee broods were widely eaten. Their entomophagy habit varies geographically where the members of Kurumba and Kattunayakan tribes residing in the Gudalur and Pandalur taluks were found to consume more insect species than the other tribes. Insects were eaten raw or roasted or cooked with the vegetables. The respondents are also aware of the therapeutic values and health benefits of insects they consume, however various factors including modernization and availability of alternate foods causes decline of insect foods.
In silico and in vitro approaches to evaluate the bioactivities of Chaetomorpha linum Ekambaram Gayathiri, Periyasamy Mahalakshmi, Thangaraj Pratheep, Palanisamy Prakash, Kuppusamy Selvam, Rengarajan Manivasagaperumal, Manikkavalli Gurunathan Ragunathan, Jayaprakash Jayanthi, Priya Kumaravel South African Journal of Botany, 2022 Seaweeds are rich in bioactive metabolites that could be used to develop new natural compounds in the pharmaceutical and cosmetic industries. The secondary metabolites, antioxidants, ADMET, Molecular docking and anticancer agents are investigated in the present study. The current research shows that seaweed, Chaetomorpha linum is vital source of natural antioxidants, which confirmed by free radical scavenging activity, DPPH, total phenolic and flavonoid content. The enzyme maximum inhibition of Glutathione respectively. It is noteworthy that glucoside action is dominant over the amylase enzyme. The anti-cancer activity of ethanol extracts showed the IC50 values 72.8 μg/mL−1 for MCF-7, respectively. The identified phytocompound absorption, distribution, metabolism and excretion assessed by SWISS ADME/T, it provides information about Human intestinal absorption and blood–brain barrier permeability. In addition, phytocompounds interaction with protein was confirmed by molecular docking. The protein 3ERT interaction of compounds 3 (-7.97 kcal/mol), compound 4 (-8.36 kcal/mol) and compound 2 (2,4-Di-tert-butylphenol -6.96 kcal/mol) provides high binding energy in comparison to other proteins. Hence, the present studies indicate that antioxidant, anti- diabetic and anticancer activity of ethanol extract as an alternative to the existing therapeutic approach to diabetic and cancer through a systematic in vitro and in silico approaches supplementing the findings.
Plant microbe based remediation approaches in dye removal: A review Ekambaram Gayathiri, Palanisamy Prakash, Kuppusamy Selvam, Mukesh Kumar Awasthi, Ravindran Gobinath, Rama Rao Karri, Manikkavalli Gurunathan Ragunathan, Jayaprakash Jayanthi, Vimalraj Mani, Mohammad Ali Poudineh, Soon Woong Chang, Balasubramani Ravindran Bioengineered, 2022 Increased industrialization demand using synthetic dyes in the newspaper, cosmetics, textiles, food, and leather industries. As a consequence, harmful chemicals from dye industries are released into water reservoirs with numerous structural components of synthetic dyes, which are hazardous to the ecosystem, plants and humans. The discharge of synthetic dye into various aquatic environments has a detrimental effect on the balance and integrity of ecological systems. Moreover, numerous inorganic dyes exhibit tolerance to degradation and repair by natural and conventional processes. So, the present condition requires the development of efficient and effective waste management systems that do not exacerbate environmental stress or endanger other living forms. Numerous biological systems, including microbes and plants, have been studied for their ability to metabolize dyestuffs. To minimize environmental impact, bioremediation uses endophytic bacteria, which are plant beneficial bacteria that dwell within plants and may improve plant development in both normal and stressful environments. Moreover, Phytoremediation is suitable for treating dye contaminants produced from a wide range of sources. This review article proves a comprehensive evaluation of the most frequently utilized plant and microbes as dye removal technologies from dye-containing industrial effluents. Furthermore, this study examines current existing technologies and proposes a more efficient, cost-effective method for dye removal and decolorization on a big scale. This study also aims to focus on advanced degradation techniques combined with biological approaches, well regarded as extremely effective treatments for recalcitrant wastewater, with the greatest industrial potential.

Study of antimicrobial protein from the hemolymph of freshwater crab Oziotelphusa senex senex and its efficacy against the human pathogens Sumalatha D, Nithya Tg, Jayanthi J, Ragunathan Mg Asian Journal of Pharmaceutical and Clinical Research, 2018 Objective: The study was done to isolate the antimicrobial protein from the freshwater crab.Methods: Antimicrobial protein was purified by sequential step of ammonium sulfate precipitation, dialysis, ion exchange chromatography, and fast protein liquid chromatography. The apparent molecular mass was determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS/MS). Primary structure analysis was done from MASCOT search engine. The antimicrobial activity of the protein was done using well diffusion method against Gram-positive and Gram-negative bacteria.Results: The molecular mass of antimicrobial protein was determined to be 33KDa by SDS-PAGE and MALDI-MS/MS. The antimicrobial protein contains eight peptides which were determined by MASCOT search engine. The protein exhibited antimicrobial activity both for Gram-positive and Gram-negative bacteria.Conclusion: The results could provide information for investigating the antimicrobial protein derived from the hemolymph of the freshwater crab Oziotelphusa senex senex.
Immune protection of Salvinia molesta D.S. mitchell in freshwater crab Oziotelphusa senex senex bacterially challenged with Aeromonas hydrophila Nithya Tg, Jayanthi J, Ragunathan Mg, Devakumar D Asian Journal of Pharmaceutical and Clinical Research, 2017 Objective: This is aimed to study the immune protection parameters of freshwater weed Salvinia molesta in bacterially challenged freshwater crab Oziotelphusa senex senex.Methods: In this present study, ethanolic extract of freshwater weed S. molesta was tested for its ability to induce immunity in bacterial challenged freshwater crab O. senex senex. Male and female crabs were challenged with Aeromonas hydrophila in relevant concentrations. The treated groups were allowed to withstand for 96 hrs. After relevant incubation time, the hemolymph of the treated crabs was subjected for various hematological, biochemical, and immunological assays.Results: Total hemocyte count increased on infection at 96 hrs, whereas significantly reduced on treatment with S. molesta at 96 hrs. All the three cell types of differential hemocytes showed significant positive changes on treatment. Levels of prophenoloxidase decreased significantly on infection and showed a significant increase in treated groups at 96 hrs of treatment.Conclusion: The present study elucidated the medicinal and pharmaceutical role of S. molesta weed which is been subjected to eradication in the recent days. Thus, the plant source can be utilized as an immunomodulatory agent and a better alternative to treat aquatic diseases.
