Clostridium perfringens Sporulation and Sporulation-Associated Toxin Production [PDF]

open access: yesMicrobiology Spectrum, 2016
ABSTRACT The ability of Clostridium perfringens to form spores plays a key role during the transmission of this Gram-positive bacterium to cause disease. Of particular note, the spores produced by food poisoning strains are often exceptionally resistant to food environment stresses such as heat, cold, and ...

A Dual Role for the Bacillus anthracis Master Virulence Regulator AtxA: Control of Sporulation and Anthrax Toxin Production

open access: yesFrontiers in Microbiology, 2018
Bacillus anthracis is an endemic soil bacterium that exhibits two different lifestyles. In the soil environment, B. anthracis undergoes a cycle of saprophytic growth, sporulation, and germination.

Impact of deoxycholate on Clostridioides difficile growth, toxin production, and sporulation

open access: yesHeliyon, 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.

Ancestral sporulation initiation [PDF]

open access: yesMolecular Microbiology, 2011
SummaryMembers of the classes Bacilli and Clostridia are able to form endospores, with clostridia representing the ancestral phylogenetic line. In contrast to Bacillus subtilis, the process of sporulation initiation at the molecular level is less well understood in Clostridium acetobutylicum, the model organism of the clostridia.

Sporulation in solventogenic and acetogenic clostridia

open access: yes, 2021
The Clostridium genus harbors compelling organisms for biotechnological production processes; while acetogenic clostridia can fix C1-compounds to produce acetate and ethanol, solventogenic clostridia can utilize a wide range of carbon sources to produce ...
