Journal of Food Safety, Volume 46, Issue 2, April 2026.This study evaluated the antimicrobial activity of 11 natural agents against eight STEC serotypes by determining their MIC and MBC at different pH and temperature conditions. Five agents demonstrating the strongest inhibitory activity in vitro were then tested at various concentrations in beef burgers inoculated with Escherichia coli O157 and stored ...

The colicin Ia receptor, Cir, is also the translocator for colicin Ia [PDF]
Molecular Microbiology, 2010 SummaryColicin Ia, a channel‐forming bactericidal protein, uses the outer membrane protein, Cir, as its primary receptor. To kill Escherichia coli, it must cross this membrane. The crystal structure of Ia receptor‐binding domain bound to Cir, a 22‐stranded plugged β‐barrel protein, suggests that the plug does not move.

Environmental Microbiology, Volume 28, Issue 3, March 2026.Using a combination of deletion mutants' construction, phenotyping of these mutants and complementary biochemical analyses, we established that the environmental Shewanella sp. ANA‐3 is using both the tetrathionate reductase Ttr and the polysulfide reductase Psr to respire tetrathionate.

Colicins of the Escherichia coli uropathogenic strain collection
Acta Biologica Slovenica, 2006 110 uropathogenic Escherichia coli (UPEC) strains were screened for colicin production and 42 (38%) of the tested UPEC strains were found to be colicinogenic.

Amount of colicin release in Escherichia coli is regulated by lysis gene expression of the colicin E2 operon. [PDF]
PLoS ONE, 2015 The production of bacteriocins in response to worsening environmental conditions is one means of bacteria to outcompete other microorganisms.

Role of the colicin A lysis protein in the expression of the colicin A operon [PDF]
Microbiology, 1997 Summary: The involvement of the cal gene, which encodes the colicin A lysis protein, in the expression of the colicin A operon is demonstrated. Colicin A synthesis by Escherichia coli was studied at various temperatures in cells containing either the wild-type colicin A operon or the colicin A operon with the cal gene deleted.

Cas9 beyond CRISPR – SUMOylation, effector‐like potential and pathogenic adaptation
The FEBS Journal, Volume 293, Issue 5, Page 1285-1296, March 2026.This Viewpoint explores the possibility that Cas9, beyond its canonical role in CRISPR immunity, may act as a host‐modulating effector during infection by Cas9‐encoding bacteria. Such a nucleomodulin‐like function could be influenced by eukaryotic post‐translational modifications, particularly SUMOylation, with potential implications for host–pathogen ...

The FEBS Journal, Volume 293, Issue 3, Page 781-805, February 2026.Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)
