Author-note | We selected seven from twenty six of gastrointestinal bacteria of Nile tilapia based on their protease release. The proteolytic isolates were phylogenetically, morphologically and biochemically characterized. Their hydrolytic capacities on various protein substrates were also determined. Our study presents insights into the phylogenetic and biochemical properties of gut-associated proteolytic strains of Nile tilapia and highlights their importance as sources of protease enzymes.

Author-note | We’ve isolated and selected, based on the biosurfactant production, four bacterial strains identified as Bacillus, Burkholderia, Providencia and Klebsiella. Their secreted surfactants showed promising activity and formed stable emulsions with a variety of hydrocarbons. The biosurfactants also exhibited inhibitory effects against several pathogenic microbes. The microbial surfactants were stable at high pH, salinity and temperatures and efficient in degrading diesel oil which suggests their prospect for application in bioremediation and oil recovery under extreme conditions.

Prevalence and Antimicrobial Resistance Phenotypes of Salmonella Species Recovered at Various Stages of Broiler Operations in Hathazari, Bangladesh

International Journal of One Health, 2021
Author-note | We analyzed the contamination frequency and antimicrobial resistance (AMR) phenotypes of Salmonella spp. recovered from various broiler samples in the retail outlets of Hathazari, Bangladesh. We found moderately high prevalence of Salmonella in the samples and high AMR among the strains. Our findings indicate that local broiler activities and food products can be a source of exposure for consumers to multidrug resistant (MDR) Salmonella and, therefore, highlight the importance for maintenance of appropriate hygiene to avoid cross-contaminations.
Biocatalysis | Insect Gut Cellulase
Evaluation of Cellulolytic Endo-1,4-β-D-Glucanase Activity in the Digestive Fluid of Adult Phytophagous Beetle Hoplasoma unicolor
Evaluation of Cellulolytic Endo-1,4-β-D-Glucanase Activity in the Digestive Fluid of Adult Phytophagous Beetle Hoplasoma unicolor

Author-note | A collaborative work performing qualitative and quantitative estimations of cellulolytic endo-1,4-β-D-glucanase activity in the gut fluid of Hoplasoma unicolor, a local beetle. We've seen this beetle actively feeding on green leaves and presumed it to must have cellulose degrading enzymes in its digestive fluid. Consequently, cellulolytic activity could be detected in plate assay and two active cellulase proteins were also seen in zymogram analysis of the gut fluid. Whether the activity is endogenous or of microbial origin, however, needs to be clarified by further investigations.
