Bacteriocins: Safe, natural antimicrobials for food preservation
TL;DR: Toxicity data exist for only a few bacteriocins, but research and their long-time intentional use strongly suggest that bacteriOCins can be safely used.
Journal ArticleDOI
Food fermentations: role of microorganisms in food production and preservation.
TL;DR: The role of lactic acid bacteria in many such fermentations and the mechanisms of antibiosis with particular reference to bacteriocins are outlined and a brief description of some important fermented foods from various countries are given.

Structure, organization, and expression of the lct gene for lacticin 481, a novel lantibiotic produced by Lactococcus lactis
TL;DR: The structural gene for the lactococcal lantibiotic lacticin 481 (lct) has been identified and cloned using a degenerated 20-mer DNA oligonucleotide based on the amino-terminal 7 amino acid residues of the purified protein this paper.

Purification, partial characterization and plasmid‐linkage of pediocin SJ‐1, a bacteriocin produced by Pediococcus acidilactici
TL;DR: Pediococcus acidilactici SJ-1, isolated from a naturally-fermented meat product, produced an antibacterial agent active against selected strains of Lactobacillus spp.
Journal ArticleDOI
Effect of Treatment Conditions on Nisin Inactivation of Gram-negative Bacteria
TL;DR: The addition of bovine serum albumin to the treatments containing nisin and EDTA did not result in a significant decrease in inhibitory action, and all of the chelators examined exhibited some inhibitory activity.
Journal ArticleDOI
Permeation of bacterial cells, permeation of cytoplasmic and artificial membrane vesicles, and channel formation on lipid bilayers by peptide antibiotic AS-48.
TL;DR: Electrical measurements suggest that AS-48 can form channels in lipid bilayers, and at low concentrations, this peptide causes permeability of liposomes to low-molecular-weight compounds without a requirement for a membrane potential.
