Abstract

Twenty three enterococci were isolated from Lighvan cheese. Enterococcal isolates identified by 16S rDNA sequencing, were evaluated for their safety and also examined for antibacterial activity and presence of the genes coding for enterocins. Four enterococcal isolates exhibited inhibitory activity against Listeria innocua and E. faecalis and harbored the bacteriocin genes (enterocins A, B, P, X and 31) too. Multiple combinations of virulence determinant genes (vanA, vanB, gelE, esp, asa1, cpd and ace) were detected in enterococcal isolates with the exception of 5 E. faecium isolates. While the isolates exhibited resistance to some antibiotics, all of them were susceptible to ampicillin and vancomycin. In conclusion, this study shows the presence of enterococci with potential biopreservative activity in Lighvan cheese; however it also warrants further research on the safety and origins of enterococci in this cheese.1
