Bile salt hydrolase activity

The LAB isolates were screened for antimicrobial activity. Out of 142 isolates only 68 isolates exhibited antimicrobial activity. Among these isolates, nine showed wide spectrum antimicrobial activity as well as good bile salt, acid and phenol tolerance.

The best results for antimicrobial activity against test pathogens and positive bile salt hydrolase activity in the presence of sodium taurodeoxycholate have also been observed in these cultures. Yoghurt cultures ST 144 and LB 144 had the highest antioxidative activity 78.30 ± 0.12, and 76.13 ± 0.12 UmL-1 , respectively. In conclusions, yoghurt cultures ST 144 and LB 144 exhibited the promising probiotic properties with additional functional properties such as antioxidant and proteolytic activity.

Thirty nine, out of 46 acid tolerant Lactobacillus spp., isolated from traditional dairy products, fermented foods and human fecal samples, were preliminary identified at genus level as Lactobacillus and evaluated for probiotic properties which included bile tolerance, simulated gastrointestinal juice, cell surface hydrophobicity, cell auto-aggregation, coaggregation and bile salts hydrolase activity.
