Napham, conventional fermented meals of the Bodo group in Assam, is produced from tender shoots of Colocasia esculenta and dried fish, and was lately granted Geographical Indication (GI) standing. Regardless of its cultural and dietary significance, its useful microbiota stays insufficiently characterised. This research aimed to determine multifunctional bacterial isolates with each purposeful and flavor-enhancing properties to be used as starter cultures. Forty-eight isolates had been screened for Gram response, enzymatic actions (protease, lipase, carbohydrate fermentation), and biosafety traits. 4 isolates (NAP/1, NAP/2, NAP/3, NAP/4) exhibiting a preliminary phenotypic security profile based mostly on in vitro screening had been evaluated for gastrointestinal stress tolerance traits, together with tolerance to acid (pH 2.0), phenol (0.4%), salt (8% NaCl), in addition to auto-aggregation capability and adhesion to hen crop epithelial cells. Amongst them, isolate NAP/4 exhibited comparatively increased tolerance, robust adhesion, and excessive auto-aggregation, and demonstrated a positive in vitro security profile, together with γ-hemolysis and broad antibiotic susceptibility. In curd and rice beverage fashions, NAP/4 enhanced sensory qualities and produced numerous taste volatiles, supporting its candidacy as a multifunctional food-fermenting isolate previous to genomic validation. 16S rRNA sequencing revealed NAP/4 as Staphylococcus sp. (GenBank accession: PQ471484.1). Collectively, these findings spotlight NAP/4 as a promising candidate for additional genomic analysis towards potential software in managed fermentation techniques and clean-label formulations. Nonetheless, whole-genome sequencing and in vivo validation stay important subsequent steps to verify security and purposeful efficacy on the molecular degree.
