Bacteriocin-producing Enterococcus casseliflavus IM 416K1, a natural antagonist for control of Listeria monocytogenes in Italian sausages (cacciatore)

The bacteriocinogenic Enterococcus casseliflavus IM 416KI (Bac(+)) isolated from Italian sausages or its bacteriocin Enterocin 416K1, with strong anti-listerial activity, were used in trials to evaluate the effect on Listeria monocytogenes NCTC 10888 in artificially inoculated Italian sausages (cacciatore). In trials with Enterocin 416KI added, L. monocytogenes showed a significant reduction as compared to the control inoculated with L. monocytogenes alone. The elimination of L. monocytogenes was only obtained in sausages added with E. casseliflavus IM 416KI Bac+. (C) 2003 Elsevier Science B.V All rights reserved.
