Identification, antibacterial and antifungal effects, antibiotic resistance of some lactic acid bacteria

Abstract A total of 74 lactic acid bacteria (LAB) isolates were obtained from yoghurt, cheese, raw milk, boza and whey. 36 strains were identified at species levels as Lactococcus lactis (15), Lc. garvieae (8) Lactobacillus plantarum (7), Enterococcus faecium (3), Leuconostoc citreum (2) and Lb.casei (1) by MALDI-TOF MS analysis. The strains were tested for antimicrobial properties using disc diffusion method against Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7, Cronobacter sakazakii, Bacillus cereus and Salmonella Typhimurium. 18 strains from available samples showe...
