Marine Bacteriocins: A Review
Like all organisms in nature, bacteria too have their own immune system and defense mechanisms. The antagonistic factors like antibiotics, bacteriocins, lysozymes, siderophores, proteases, and/or hydrogen peroxide and the alteration of pH values by organic acids produced either singly or in combination act as defense substances. Bacteriocins are potent antimicrobial peptides and proteins, found...
متن کاملCommercial ampholytes used for isoelectric focusing may interfere with bioactivity based purification of antimicrobial peptides.
BioRad's Rotofor system has been frequently used for the purification of proteins and smaller peptides such as bacteriocins. In this study, we report that some commercially available ampholytes used with the Rotofor isoelectric focusing system possess antimicrobial activity, which may interfere with the purification of bacteriocins and bacteriocin-like substances.
متن کاملBacteriocin production by strains of Neisseria meningitidis.
Kingsbury, David T. (Naval Medical Research Institute, Bethesda, Md.). Bacteriocin production by strains of Neisseria meningitidis. J. Bacteriol. 91:1696-1699. 1966.-Strains of Neisseria meningitidis produce substances inhibitory to other strains of meningococcus. These substances are nontransmissible and show a high degree of strain specificity. The properties of one of these substances resemb...
متن کاملThe continuing story of class IIa bacteriocins.
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 the...
متن کاملThe Role of Bacteriocins in Rumen Microbial Ecology
In recent years there has been an increased interest in bacteriocins, primarily among the lactic acid bacteria, as a result of their applications in food preservation. There has been very little research on the occurrence of bacteriocin production among anaerobic bacteria. Recently, we reported a high incidence of bacteriocin-like inhibitory activity in isolates of the rumen anaerobe Butyrivibr...
