Identification of the catalytic motif of the microbial ribosome inactivating cytotoxin colicin E3 [PDF]

open access: yes, 2004
Colicin E3 is a cytotoxic ribonuclease that specifically cleaves 16S rRNA at the ribosomal A-site to abolish protein synthesis in sensitive Escherichia coli cells.

A Review: The Fate of Bacteriocins in the Human Gastro-Intestinal Tract: Do They Cross the Gut–Blood Barrier?

open access: yesFrontiers in Microbiology, 2018
The intestinal barrier, consisting of the vascular endothelium, epithelial cell lining, and mucus layer, covers a surface of about 400 m2. The integrity of the gut wall is sustained by transcellular proteins forming tight junctions between the epithelial

In vitro and in vivo production and split-intein mediated ligation (SIML) of circular bacteriocins

open access: yesFrontiers in Microbiology, 2022
Circular bacteriocins are antimicrobial peptides produced by bacteria that after synthesis undergo a head-to-tail circularization. Compared to their linear counterparts, circular bacteriocins are, in general, very stable to temperature and pH changes and

Efficacy of nisin A and nisin V semi-purified preparations alone and in combination with plant essential oils to control Listeria monocytogenes [PDF]

open access: yes, 2015
peer-reviewedThe foodborne pathogenic bacterium Listeria is known for relatively low morbidity and high mortality rates reaching up to 25-30%. Listeria is a hardy organism and its control in foods represents a significant challenge.

Transcriptional profiling of colicin-induced cell death of Escherichia coli MG1655 identifies potential mechanisms by which bacteriocins promote bacterial diversity [PDF]

open access: yes, 2004
We report the transcriptional response of Escherichia coli MG1655 to damage induced by colicins E3 and E9, bacteriocins that kill cells through inactivation of the ribosome and degradation of chromosomal DNA, respectively. Colicin E9 strongly induced the

BACTERIOCINS OF Lactobacillus LF221 STRAIN

open access: yesActa Agriculturae Slovenica, 1998
LF221 strain is a Lactobacillus isolate from a baby’s faeces that was previously found to produce bacteriocin(s) with inhibitory activity against a wide range of bacterial species including some pathogenic and food-spoilage (Bacillus cereus, Clostridium ...

Purification and Partial Characterization of a Bacteriocin Produced by Lactobacillus pentosus 124-2 Isolated from Dadih

open access: yesApplied Sciences, 2023
The fermentation process results in the presence of lactic acid bacteria (LAB). Traditional fermented buffalo milk from the Indonesian province of West Sumatra is known as dadih.

Quorum sensing-controlled gene expression in lactic acid bacteria [PDF]

open access: yes, 1998
Quorum sensing in lactic acid bacteria (LAB) involves peptides that are directly sensed by membrane-located histidine kinases, after which the signal is transmitted to an intracellular response regulator. This regulator in turn activates transcription of

Lactococcus lactis subsp. lactis as a natural anti-listerial agent in the mushroom industry [PDF]

open access: yes, 2019
peer-reviewedMushroom growth substrates from different commercial producers of mushrooms (Agaricus bisporus) were screened for the presence of bacteria with potential for use as biocontrol agents for controlling Listeria monocytogenes in the mushroom ...
