Abstract:
Listeria innocua strain Lin11 was used to compare the inhibitory activity of two bacteriocins (nisin A and pediocin AcH) in a decontamination process consisting of soaking artificially contaminated pieces of raw pork meat in a bacteriocin-containing solution before they were ground and stored aerobically at 5°C. Nisin A proved to be considerably more efficient than pediocin AcH, but generally after two days surviving bacteria in meat treated with each bacteriocin resumed growth at a rate similar to that of the control. Increasing the nisin concentration in the decontaminating bath resulted in

Abstract:
Fourteen bacteriocin-producing strains from the genera Lactobacillus, Leuconostoc, Pediococcus, and Lactococcus were evaluated for their ability to inhibit the growth of eight strains of Listeria monocytogenes. Seven strains of lactic acid bacteria were antagonistic toward L. monocytogenes by deferred antagonism testing on agar. Cell-free supernatants from cultures of three of the seven bacteriocin-producing strains which inhibited growth of L. monocytogenes in deferred antagonism testing also inhibited growth in well diffusion assays. The eight strains of L. monocytogenes were identical in th

Abstract:
ABSTRACT Listeria innocua 743 produces an inhibitory activity demonstrating broad-spectrum inhibition of Listeria monocytogenes isolates. Gel-electrophoretic analysis of culture supernatants indicated that two inhibitors with different molecular weights were produced by this strain. Insertion of Tn917into a 2.9 Kb plasmid (pHC743) generated mutants with either an impaired ability or a loss in ability to produce one of the inhibitors. Sequence analysis of the transposon insertion regions revealed the presence of two continuous open reading frames, the first encoding a new pediocin-like bacterio

Listeria monocytogenes inhibition by Carnobacterium strains and crude bacteriocins on sterile and commercial vacuum-packed cold-smoked salmon stored at 4°C and 8°C was investigated. Carnobacterium piscicola V1 was bactericidal against L. monocytogenes at the two temperatures, whereas Carnobacterium divergens V41 presented a bacteriostatic effect. C. piscicola SF668 delayed L. monocytogenes growth at 8°C and had a bacteriostatic effect at 4°C. Listeria growth was not affected by a non–bacteriocin-producing C. piscicola.

Abstract:
Lactic acid bacteria produce a variety of small molecular weight compounds, which have antimicrobial properties. Such substances are: organic acids, alcohols, carbon dioxide, diacetyl, hydrogen peroxide and bacteriocins. Many of these compounds have a wide inhibitory spectrum but the bacteriocins are able to inhibit species, namely, related with the bacteriocin-producing strain. In the last years bacteriocins have gained a lot of concern because some of them are able to inhibit the growth of pathogenic bacteria, like Listeria monocytogenes.

Intestinal microbiota exerts protective effects against the infection of various bacterial pathogens, including Listeria monocytogenes, a major foodborne pathogen whose infection can lead to a disease (listeriosis) with a high fatality rate. As a strategy to mitigate the action of the intestinal microbiota, pathogens often produce antimicrobial proteinaceous compounds such as bacteriocins. In this review, we summarize the information currently available for the well-characterized L. monocytogenes bacteriocin listeriolysin S, with the emphasis on its intriguing mode of action as a virulence fac

SUMMARY Many bacteria produce antimicrobial peptides, which are also referred to as peptide bacteriocins. The class IIa bacteriocins, often designated pediocin-like bacteriocins, constitute the most dominant group of antimicrobial peptides produced by lactic acid bacteria. The bacteriocins that belong to this class are structurally related and kill target cells by membrane permeabilization. Despite their structural similarity, class IIa bacteriocins display different target cell specificities.

Abstract:
During the last few years, a large number of new bacteriocins produced by lactic acid bacteria (LAB) have been identified and characterized. LAB-bacteriocins comprise a heterogeneous group of physicochemically diverse ribosomally-synthesized peptides or proteins showing a narrow or broad antimicrobial activity spectrum against Gram-positive bacteria. Bacteriocins are classified into separate groups such as the lantibiotics (Class I); the small (<10 kDa) heat-stable postranslationally unmodified non-lantibiotics (Class II), further subdivided in the pediocin-like and anti Listeria bacterioci
