Sreening of Bacteriocin-Producing Bacteria from Various Sources

In this study, 1,602 bacterial strains were isolated from various sources and 18 isolates including 12 strains of Lactobacillus, five of Lactococcus lactis and one of Pseudomonas fluorescens, showed bacteriocin-like activity. These isolates were all from Kimchi and Tsukemono. Five strains of Lc. lactis inhibited Listeria monocytogenes, Clostridium difficile, C. perfringens and vancomycin resistant Enterococcus, while P. fluorescens inhibited methicillin resistant Staphylococcus aureus and Salmonella Enteritidis. However, Lactobacillus strains showed no activity against pathogens among these isolates.
