| Abstract: | The search for lactic acid bacteria (LAB) producing bacteriocin-like inhibitory substances (BLISs) was performed in traditional Azerbaijan cheeses. Eight strains have been isolated and identified, four of which (S1a, S2, Q2b, and M1b) were identified as Lactobacillus buchneri. The remaining four strains (M3a, A4b, Q4a, and A3) were identified as L. pentosus, L. brevis, L. fermentum, and L. collinoides, respectively. Antimicrobial agents of all isolated LAB strains suppressed the growth of Lactobacillus bulgaricus 340, Escherichia coli, Enterococcus durans, and Listeria innocua. Saccharomyces cerevisiae and Candida pseudotropicalis were resistant to these BLISs. Proteinase K and trypsin completely inactivated BLIS whereas lipase and amylase partially inactivated BLIS. |
