ABSTRACT The ability of glycinecin A, a bacteriocin derived from Xanthomonas campestris pv. glycines 8ra, to kill closely related bacteria has been demonstrated previously by our group (S. G. Heu et al., Appl. Environ. Microbiol. 67:4105-4110, 2001). In the present study, we aimed at determining the glycinecin A-induced cause of death. Treatment with glycinecin A caused slow dissipation of membrane potential and rapid depletion of the pH gradient. Glycinecin A treatment also induced leakage of… 
Prevalence of bacteriocinogenic Rhizobium spp. in mungbean (Vigna radiata)
The present work was undertaken to ascertain prevalence of bacteriocinogenic Rhizobium spp. in mungbean (Vigna radiata). Samples of rhizospheric soil and nodules were plated onto CRYEMA medium,
Nodule occupancy in relation to bacteriocin production by Rhizobium spp.
TLDR
Dual inoculation strategy of using a nitrogen fixer (indicator strain) and bacteriocin producing Rhizobium isolates gave significantly better results for nodulation, plant growth and yield attributes.
The Biofilm Inhibitor Carolacton Disturbs Membrane Integrity and Cell Division of Streptococcus mutans through the Serine/Threonine Protein Kinase PknB
TLDR
The data suggest that carolacton acts by interfering with PknB-mediated signaling in growing cells by causing leakage of cytoplasmic content and cell death at low pH, which is due to the strong acidification occurring during biofilm growth.
Plant lectin-like antibacterial proteins from phytopathogens Pseudomonas syringae and Xanthomonas citri.
TLDR
The functional characterization of LlpA proteins from two different phytopathogenic γ-proteobacterial species expands the lectin-like bacteriocin family beyond the Pseudomonas genus and suggests its involvement in competition among closely related plant-associated bacteria with different lifestyles.
Consequences of daptomycin-mediated membrane damage in Staphylococcus aureus.
TLDR
Data show that daptomycin-induced loss of Mg(2+) and ATP occurs in conjunction with the previously reported leakage of K(+) and membrane depolarization, and it is proposed that the lethal activity of d aptomycin is not simply due to loss of K (+) and probably involves more general damage to the membrane.
A potential protective culture; halophilic Bacillus isolates with bacteriocin encoding gene against Staphylococcus aureus in salt added foods
TLDR
The research aimed to investigate and isolate halophilic bacteria in salt-fermented foods with active inhibitory effect against Staphylococcus aureus and selected B. subtilis as a skim milk–based protective culture which significantly helped prolong freshness of the cheese over 16 days without affecting its physicochemical properties, particularly pH.
Genus-specific distribution and pathovar-specific variation of the glycinecin R gene homologs in Xanthomonas genomes
TLDR
The glyR gene can serve as a useful genus-specific and pathovar-specific DNA marker for Xanthomonas according to the patterns resulted from Southern hybridization using the genomic digests.
Purification, Characterization, Site-Directed Mutagenesis And Mode Of Action Studies Of The Bacillus Bacteriocin Thurincin H
TLDR
Thurincin H exhibited a broad antimicrobial activity against 22 tested bacterial strains among 6 different genera including Bacillus, Carnobacterium, Geobacillus, Enterococcus, Listeria, and Staphylococcus and there was no detectable activity against any of the selected yeast or fungi.
Scientific Opinion on the pest categorisation of Xanthomonas campestris pv. vesicatoria (Doidge) Dye
The European Commission requested the EFSA Panel on Plant Health to perform the pest categorisation for Xanthomonas campestris pv. vesicatoria, which is the causal agent of bacterial spot of tomato
Engineering bacteriocin-mediated resistance against plant pathogenic bacteria in plants
TLDR
It is demonstrated that active putidacin L1 (PL1) can be expressed at high levels in planta and expression of PL1 provides effective resistance against diverse pathovars of Ps, and proved that strains which evolve to become insensitive to PL1; lose their O-antigen, exhibit reduced motility and are less virulent in PL1 transgenic plants.

Improvement in the Stability of Glycinecin A through Protein Fusion of the Two Structural Components
TLDR
It is reported that purified glycinecin A is composed of two polypeptides, is active over a wide range of pH (6 to 9), and is stable at temperatures up to 60oC.
gly Gene Cloning and Expression and Purification of Glycinecin A, a Bacteriocin Produced by Xanthomonas campestris pv. glycines 8ra
TLDR
Glycinecin A is a heterodimer consisting of 39- and 14-kDa subunits, as revealed through size exclusion chromatography and cross-linking analysis, and both genes are translated as bacteriocin precursors that include N-terminal leader sequences.
Lacticin 3147, a Broad-Spectrum Bacteriocin Which Selectively Dissipates the Membrane Potential
TLDR
The results suggest that lacticin 3147 is a pore-forming bacteriocin which acts on a broad range of gram-positive bacteria, including Listeria monocytogenes, and Bacillus subtilis.
Effect of GlycinecinA on the Control of Bacterial Leaf Spot of Red Pepper and Bacterial Leaf Blight of Rice
TLDR
The bacteriocin is a potential control agent for bacterial diseases and its control efficacy was as high as, or even higher than, the chemical treatment of copper hydroxide.
Characterization of Serracin P, a Phage-Tail-Like Bacteriocin, and Its Activity against Erwinia amylovora, the Fire Blight Pathogen
ABSTRACT Serratia plymithicum J7 culture supernatant displayed activity against many pathogenic strains of Erwinia amylovora, the causal agent of the most serious bacterial disease of apple and pear
Characterization of Enterocoliticin, a Phage Tail-Like Bacteriocin, and Its Effect on Pathogenic Yersinia enterocolitica Strains
TLDR
Yersinia enterocolitica 29930 produces a bacteriocin, designated enterocoliticin, that shows inhibitory activity against enteropathogenic strains of Y. enterocol itica belonging to serogroups O:3, O:5,27 and O:9, indicating that enterocolitein has channel-forming activity.
Mode of action of modified and unmodified bacteriocins from Gram-positive bacteria.
TLDR
This work has demonstrated that for many bacteriocins, generalised membrane disruption models as elaborated for amphiphilic peptides cannot adequately describe the bactericidal action; rather, specific targets seem to be involved in pore formation and other activities.
Antibacterial and Antimembrane Activities of Cecropin A in Escherichia coli
TLDR
The results indicate that differences in the concentration dependences of membrane permeabilization and depolarization seen in synthetic vesicles are not manifested in whole bacteria, suggesting that the bactericidal mechanism of cecropin A is related to membrane permeability.
Lactococcin G is a potassium ion-conducting, two-component bacteriocin
TLDR
Data suggest that the bactericidal effect of lactococcin G is due to the formation of potassium-selective channels by the alpha and beta peptides in the target bacterial membrane.
Bacteriocins: nature, function and structure.
TLDR
This review summarises the classification, biochemical nature, morphology and mode of action of bacteriocins as well as their genetic determinants and the microbiological relevance of these bactericidal agents.
