Probiotic potential of <i>Bacillus licheniformis</i> isolated from indigenous traditional fermented beverage

Abstract

In this study, a potential probiotic microorganism A3 isolated from <i>Angoori</i> was subjected to probiotic characterization. The isolate A3 was identified as <i>Bacillus licheniformis</i>. The strain showed broad antagonism against most pathogens, good auto-aggregation capacity, i.e., greater than 40% after 5 hrs, high acid tolerance showing survival of 75.4 % at <i>p</i>H 1.0 for 60 min and bile salt tolerance ranging from 80.16% to 84.41%. The isolate was found to be highly sensitive towards all the 16 antibiotics tested. These results indicated that <i>B. licheniformis</i> A3 isolated from <i>Angoori </i> had a promising potential as good probiotic and could further be exploited for its commercial use.
