Bacteriocin from Honeybee Beebread <i>Enterococcus</i> <i>avium</i> , Active against <i>Listeria</i> <i>monocytogenes</i>

Abstract

Enterococcus avium isolated from Apis mellifera beebread produces a thermoresistant bacteriocin with a strain-dependent inhibitory effect on Listeria and without effect on gram-negative bacteria. The bacteriocin appeared to be a polypeptide of about 6 kDa. Genetic analyses revealed no extrachromosomal material in E. avium.
