Özet

Twelve strains of enterococci isolated from white cheese samples obtained from different regions of Turkey were screened for their antimicrobial activity against some Gram-positive and Gram-negative food-borne pathogens and contaminating bacteria, also against themselves and some other lactic acid bacteria (LAB), including some species of lactococci, lactobacilli and Leuconostoc. Antimicrobial activity was confirmed for all 12 strains, including six Enterococcus faecium, two Enterococcus faecalis and four Enterococcus durans. Antimicrobial agents produced by these enterococci exhibited a spectrum of activity, which is mainly directed against food-borne pathogens, specially Listeria monocytogenes and Bacillus cereus and some other Bacillus spp. and also some enterococci. Tested LAB was insensitive to inhibitory agents produced by them.
