This study
demonstrated that bioactive peptides generated during fermentation with L. helveticus showed a good degree of
inhibition including zone of inhibition -17mm against Gram’s negative bacteria and 15mm for Gram’s positive bacteria
at 5.1 pH for 20 hours of incubation and combination of Lactococcus and Lactobacilli at 4% inoculation showed a good
degree of inhibition zone 15.6 against Gram’s positive bacteria and 12mm for Gram’s negative bacterial when kept at
3.2 pH for 28 hours of incubation
