Probiotic potential and antimicrobial activity of bacteria isolated from fermented foods

Probiotics play a significant role in improving human health and are beneficial for the gastrointestinal tract. In this study, lactic acid bacteria were isolated from different dairy products collected from different locations of Rohtak and Hisar (Haryana). All these isolates were tested and selected based on their ability to resist low and high pH, ability to survive in the presence of bile salt concentration and their antagonistic activity against pathogenic bacteria. Investigation on probiotics study supported that they are beneficial to human beings and act as a barrier against pathogenic bacteria.
