Molecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

The role of Spo0A in regulation of Ssp4 production.
, 2013 (A) Total DNA isolated from SM101, spo0A null mutant IH101, and the complementing strain IH101(pMRS123), or plasmid pMRS123 alone, was subjected to PCR analysis using spo0A-specific internal primers CPP68 and CPP69 [17].

Under-detection of endospore-forming Firmicutes in metagenomic data
Computational and Structural Biotechnology Journal, 2015 Microbial diversity studies based on metagenomic sequencing have greatly enhanced our knowledge of the microbial world. However, one caveat is the fact that not all microorganisms are equally well detected, questioning the universality of this approach ...

High- and Low-Threshold Genes in the Spo0A Regulon of Bacillus subtilis [PDF]
Journal of Bacteriology, 2005 ABSTRACT The master regulator for entry into sporulation in Bacillus subtilis is the response regulator Spo0A, which directly governs the expression of about 121 genes. Using cells in which the synthesis of Spo0A was under the control of an inducible promoter or in which ...

Chemical and Stress Resistances of Clostridium difficile Spores and Vegetative Cells
Frontiers in Microbiology, 2016 Clostridium difficile is a Gram-positive, sporogenic and anaerobic bacterium that causes a potentially fatal colitis. C. difficile enters the body as dormant spores that germinate in the colon to form vegetative cells that secrete toxins and cause the ...

Microbial Biotechnology, Volume 18, Issue 11, November 2025.This study demonstrates that the production of surfactin by B. subtilis R31 needs to be balanced. Excessive surfactin will weaken the colonisation ability and disease control effect of the strain. By targeting the regulation of the surfactin signalling pathway, synthetic microbial communities can be designed for sustainable disease control.

The formation and visualisation of three day old biofilms in the spo0A mutant.
, 2012 The biofilms produced attached to a TC flask were compared for R20291, R20291_spo0A::CT and R20291_spo0A::CT::pspo0A. These attached biofilms were matured over a three day period, before they were detached from the plastic by agitation for visualisation ...

Impact of deoxycholate on Clostridioides difficile growth, toxin production, and sporulation
Heliyon, 2020 Purpose: Bile acids play an important role in Clostridioides difficile life cycle. Deoxycholate (DCA), one of the most abundant secondary bile acids, is known to inhibit vegetative growth and toxin production.
