    Abstract

    A total of 203 lactic acid bacteria (LAB) isolated from vegetables and traditional
    fermented food products of India such as idli batter, dhokla batter and dahi were
    screened for exopolysaccharide (EPS) production. Based on the amount of EPS
    produced, 17 LAB isolates were selected for biochemical and genetic
    characterization using 16S rRNA gene sequencing. The isolates were belonging
    to the genera Lactobacillus, Weissella and Pediococcus. In vitro examination
    was performed to evaluate their probiotic potential. Resistance to low pH and 0.3
    % bile salts was studied. Bile salt hydrolase (BSH) activity, susceptibility to
    various antibiotics and antimicrobial activity against the non pathogenic E. coli
    K12 were also investigated. The results showed that the isolates could not grow
    in the presence of oxbile however some survived exposure to it for 2.5 h. Some
    isolates were able to grow in the presence of sodium taurocholate and showed
    considerable antimicrobial activity against E. coli K12. Five isolates were showing
    BSH activity which is reported for the genus Weissella for the first time. The
    results suggest that traditional fermented products could be an alternative and
    readily available
