The in vitro inhibitory activity of enterocin-35 produced by Enterococcus faecium CRL 35, was studied against Listeria monocytogenes, isolated from seafoods. Optimal growth conditions of the enterocin-35 producing strain, for higher bacteriocin production and improve the extraction and purification of these peptides, were applied. A crude extract of enterocin-35 was assayed in a frozen seafood artificially contaminated with Listeria monocytogenes isolate, simulating at laboratory scale an eventual application of this biopreservant in a routine production process at factory level. The feasibility of biopreservation of seafoods by means of bacteriocins is proposed and discussed.
