Brochocin-C, a new bacteriocin produced by Brochothrix campestris

Brochocin-C, a new bacteriocin produced by Brochothrix campestris.

Brochotrix campestris ATCC 43754 produces a bacteriocin inhibitory towards Brochothrix thermosphacta, lactobacilli, Listeria spp., and other gram-positive bacteria. This antimicrobial agent is heat stable, sensitive to proteases, catalase insensitive, and free of organic acids. No phage particles were detected by transmission electron microscopy. Muramidase activity was not detected in the prep...

The outer membrane of gram-negative bacteria inhibits antibacterial activity of brochocin-C.

Brochocin-C is a two-peptide bacteriocin produced by Brochothrix campestris ATCC 43754 that has a broad activity spectrum comparable to that of nisin. Brochocin-C has an inhibitory effect on EDTA-treated gram-negative bacteria, Salmonella enterica serovar Typhimurium lipopolysaccharide mutants, and spheroplasts of Typhimurium strains LT2 and SL3600. Brochocin-C treatment of cells and spheroplas...

gly gene cloning and expression and purification of glycinecin A, a bacteriocin produced by Xanthomonas campestris pv. glycines 8ra.

Glycinecin A, a bacteriocin produced by Xanthomonas campestris pv. glycines, inhibits the growth of X. campestris pv. vesicatoria. We have cloned and expressed the genes encoding glycinecin A in Escherichia coli. Recombinant glycinecin A was purified from cell extracts by ammonium sulfate precipitation followed by chromatography on Q-Sepharose, Mono Q (ion exchange), and size exclusion columns....

Detection and Characterization of Weissellicin 110, a Bacteriocin Produced by Weissella cibaria

Background: Weissellicin 110 is the only bacteriocin reported in Weissella cibaria up to now. This bacteriocin represents several unique features. This is the first report on the gene sequence that encodes for the bacteriocin. Objectives: Providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives. Materi...
