Antimicrobial Components of Lactic Acid Bacteria
TL;DR: A review of low molecular weight, organic antimicrobial metabolite components that are produced by Lactobacillus can be found in this article, along with a more detailed overview of the more complex bacteriocins produced by Bacteria.
Journal ArticleDOI
The dermaseptin precursors : a protein family with a common preproregion and a variable c-terminal antimicrobial domain
TL;DR: The remarkable similarity between preproregions of precursors that give rise to peptides with very different primary structures, conformations and activities suggests that the corresponding genes originate from a common ancestor.
Journal ArticleDOI
Bacteriocins as food preservatives: Challenges and emerging horizons
TL;DR: The desirable characteristics of the bacteriocins which earn them a place in food preservation technology, the success story of the same inVarious food systems, the various challenges and the strategies employed to put them to work efficiently in various food systems has been discussed in this review.
Journal ArticleDOI
The rpoN (sigma54) gene from Listeria monocytogenes is involved in resistance to mesentericin Y105, an antibacterial peptide from Leuconostoc mesenteroides.
TL;DR: Results demonstrate that the L.monocytogenes rpoN gene encodes a new sigma54 factor, which is responsible for the resistance phenotype in L. monocytogene and promoted transcription of a sigma 54-dependent operon in the presence of the associated regulator.

Purification and Characterization of a Bacteriocin Produced by Lactobacillus lactis Isolated from Marine Environment
TL;DR: The study revealed the possibility of using bacteriocin as a food preservative and the L. lactis strain as probiotic and showed broad range of antibacterial activity against some major food borne pathogens.

Genetics of bacteriocins produced by lactic acid bacteria
TL;DR: The biochemical and genetic characteristics of these antimicrobial proteins are reviewed and common elements are discussed between the different classes of bacteriocins produced by these Gram-positive bacteria.
Journal ArticleDOI
Bacteriocins of lactic acid bacteria
TL;DR: The range of inhibitory activity by bacteriocins of lactic acid bacteria can be either narrow, inhibiting only those strains that are closely related to the producer organism, or wide, inhibited a diverse group of Gram-positive microorganisms as mentioned in this paper.
Journal ArticleDOI
Nisin treatment for inactivation of Salmonella species and other gram-negative bacteria.
TL;DR: It is demonstrated that nisin is bactericidal to Salmonella species and that the observed inactivation can be demonstrated in other gram-negative bacteria.
Journal ArticleDOI
Characterization of the nisin gene cluster nisABTCIPR of Lactococcus lactis. Requirement of expression of the nisA and nisI genes for development of immunity
TL;DR: Transcription analyses of several L. lactis strains indicated that an expression product of the nisA gene, together with NisR, is required for the activation of nisinA transcription, indicating that NisI plays a role in the immunity mechanism.

Mode of action of the peptide antibiotic nisin and influence on the membrane potential of whole cells and on cytoplasmic and artificial membrane vesicles
E Ruhr,Hans-Georg Sahl +1 more
TL;DR: The data suggest that the cytoplasmic membrane is the primary target and that membrane disruption accounts for the bactericidal action of nisin.
