Abstract: (573 Views)
Bacteriocins are proteins produced by bacteria, especially lactic acid bacteria, which have antimicrobial properties and are used to preserve foods. L50A and l50B are the compounds produced by some Enterococcus faeicum strains. The present study was conducted to isolate and determine the frequency of enterocin L50A and L50B genes in E. faecium isolates from meat in Shahrekord, Iran. In this research, 80 meat samples were prepared, and the prevalence of l50A and l50B enterocin genes were studied. The bacteria were isolated using biochemical microbiology methods such as the bile esculin test, growth in NaCl 6.5%, pyruvate fermentation, and molecular techniques. In the presence of specific primers for enterocin genes, the frequency of l50A and l50B genes was determined. In this research, out of a total of 80 studied samples, 66 samples (82.5%) were infected with Enterococcus, of which 35 samples (43.75%) were infected with E. faecium bacteria. L50A was determined in 15 isolates (42.85%), and L50B was determined in 14 isolates (40%). Due to the relatively high contamination of E. faecium in meat, other studies for antimicrobial properties of enterocrins produced by this bacterium are recommende
