Exploring the probiotic potentiality and antibacterial activity of idli batter isolates of lactic acid bacteria from West Bengal, India

Abstract Background The lactic acid bacteria (LAB), from diverse sources, are of great importance as probiotics, and several authors around the globe have reported LAB, isolated various fermented foods, potential antimicrobial agents. current study explored antibacterial activity probiotic property idli batter isolates for first time Malda (West Bengal, India). Results LAB procured fresh samples had against pathogenic well food-borne with zone diameter inhibition 16, 18 23 mm concentrations 25, 50 75 μl/well, respectively, determined by agar-well diffusion method. identification was executed through biochemical tests, 16S rRNA gene sequencing phylogenetic analysis. batter: LMEM1001 LMEM1002, showed maximum (96.81% 95.20%, respectively) similarities Lactiplantibacillus pentosus plantarum, whereas isolates, LMEM1006 LMEM1008, (96.11% 98.40%, plantarum Limosilactobacillus fermentum, respectively. Safety profiling using antibiogram, DNase gelatinase tests. Conclusions batter-derived lactobacilli been demonstrated good which displayed excellent clinical bacteria. Overall, might be useful probiotics human consumption biotherapeutics in combating bacterial antibiotic resistance.
