Evidence on inhibition of Listeria monocytogenes by divercin V41 action.
OBJECTIVE
The aim of this study was to investigate the role of divercin V41 in inhibition and prevention of Listeria monocytogenes.


RESULTS
Carnobacterium divergens V41 deficient in bacteriocin production was isolated and characterized by enzyme-liked immunosorbent assay, multiplex polymerase chain reaction and bacteriocin diffusion test. Carnobacterium divergens V41 (divercin+) and Carnobacterium divergens V41C9 (divercin-) were grown in the presence of L. monocytogenes in smoked salmon model medium. Carnobacterium divergens V41, but not C. divergens V41C9, was able to inhibit growth of L. monocytogenes. The results indicate that inhibition of L. monocytogenes in the presence of C. divergens V41 is because of the production of divercin V41 and not to a nutritional advantage.


CONCLUSIONS
Carnobacterium divergens V41 may be a promising agent in food safety.


CONCLUSIONS
The study demonstrates a potential use of a bacteriocin producing lactic acid bacteria in the area food protection.
