Aims: The aim of this study was to investigate the role of divercin V41 in inhibition and prevention of Listeria monocytogenes . Methods and 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. Significance and Impact of the Study: The study demonstrates a potential use of a bacteriocin producing lactic acid bacteria in the area food protection.
