Summary: The present study evaluated the potential of Asparagus racemosus starter-based rice fermented foods in combating obesity, hyperglycemia, and depression. The fermented food increased food intake, body weight, organ weight, fat masses, and improved lipid profiles in obese mice. It also upregulated fatty acid oxidation and downregulated adipogenesis-related genes, leading to improved glucose metabolism and insulin sensitivity. The fermented food modulated gut microbiota and increased short-chain fatty acid levels. Additionally, it mitigated obesity-associated cognitive impairments. Therefore, this fermented food could serve as a natural therapeutic for obesity and its associated psychological and pathophysiological ailments.

Summary: This study introduced an innovative strategy to combat fungal infection in pulses by inactivating the secreted invasins of fungal phytopathogens using natural phytochemicals. In silico docking study identified quercetin, naringin, epigallocatechin gallate, curcumin, and cinnamic acid as efficient phytochemicals for inhibiting fungal invasive enzymes. The extracted phytochemicals were found to be cytosafe and effective in preventing the growth of the isolated pathogen, with minimal inhibitory concentrations ranging from 170 to 320 mg/L. Long-term storage of white lentil seeds with these phytochemical mixtures showed complete protection against fungal infection. This work demonstrates the potential of using natural preservatives to store pulses and mitigate the adverse effects of chemical preservatives on the ecosystem.

Summary: The aim of this study was to isolate a highly beneficial probiotic bacterium capable of producing glutathione. The isolated strain, Bacillus amyloliquefaciens KMH10, exhibited antioxidative activity (77.7 ± 2.56) and several other essential probiotic attributes. A consortium of lignocellulolytic enzymes was used to saccharify banana peel, resulting in the production of 65.71 g/L sugar to support optimal glutathione production of 181 ± 4.56 mg/L, which was 1.6 times higher than the control. Therefore, this probiotic bacteria could serve as an effective resource for glutathione and be used as natural therapeutics for the prevention/treatment of inflammation-related gastric ailments, as well as an effective producer of glutathione using valorized banana waste that has excellent industrial relevance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
