Genetics of Bacteriocin Production in Lactic Acid Bacteria
TL;DR: Rbosomally synthesized antimicrobial peptides in bacteria are generally referred to as bacteriocins, and are produced by numerous Gram-positive and Gram-negative bacteria.

Conformation-activity relationship of a novel peptide antibiotic: structural characterization of dermaseptin DS 01 in media that mimic the membrane environment.
TL;DR: A new dermaseptin, named DS 01, from the skin secretion of Phyllomedusa oreades, showed not only strong antibacterial properties against Gram‐positive and Gram‐negative bacteria but also antiprotozoan activity in the μM range.

Characterization of bacteriocins produced by lactic acid bacteria from fermented beverages and optimization of starter cultures
Von Mollendorff,Johan Wilhelm +1 more
TL;DR: Both strains were detected in boza after 7 days of storage at 4 oC and repressed the growth of Lactobacillus sakei DSM 20017, indicating that at least one of the bacteriocins is produced in situ.

Exopolysaccharides from Lactic Acid Bacteria and Bifidobacteria
Patricia Ruas-Madiedo,Borja Sánchez,Claudio Hidalgo-Cantabrana,Abelardo Margolles,Andrew P. Laws +4 more
TL;DR: These outer cellular molecules act as a barrier to protect bacteria against adverse environmental conditions and could also be sensors to communicate with other biotic and abiotic components of the ecosystems they inhabit.

Determination of comparative minimum inhibitory concentration (MIC) of bacteriocins produced by enterococci for selected isolates of multi-antibiotic resistant Enterococcus spp
TL;DR: The present survey may address the potential applicability of antimicrobial peptides with bactericidal or bacteriostatic activity in alleviating the problems of antibiotic resistance.

Journal ArticleDOI
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.
