Pathway for H2O2 and O2 detoxification in Clostridium acetobutylicum [PDF]

Microbiology, 2009
An unusual non-haem diiron protein, reverse rubrerythrin (revRbr), is known to be massively upregulated in response to oxidative stress in the strictly anaerobic bacterium Clostridium acetobutylicum. In the present study both in vivo and in vitro results demonstrate an H2O2 and O2 detoxification pathway in C. acetobutylicum involving revRbr, rubredoxin

Molecular Chain Elongation Mechanism for n‐Caproate Biosynthesis by Megasphaera Hexanoica

Advanced Science, Volume 12, Issue 44, November 27, 2025.
The medium‐chain carboxylate‐producing microbe Megasphaera hexanoica is analyzed through genomics, transcriptomics, and metabolic engineering. The n‐caproate biosynthetic pathway is reconstructed in Escherichia coli, highlighting MhTHL as a key β‐ketothiolase. Structural analysis and mutagenesis reveal that MhTHL has a distinct substrate‐binding pocket,

Effects of Temperature, pH, and Agitation on Growth and Butanol Production of Clostridium acetobutylicum, Clostridium beijerinckii, and Clostridium saccharoperbutylacetonicum

Environmental and Climate Technologies
Butanol is a promising alternative to fossil-derived fuels. Clostridium genus bacteria are known for their ability to produce butanol as one of the metabolites, however, at the moment this solution is not economically viable.

Gut Microbiota‐Bile Acid Metabolism Axis Drive Anti‐Diabetic Effects of Polygonatum cyrtonema Polysaccharide on Glycolipid Metabolism and Intestinal Inflammation

Food Frontiers, Volume 6, Issue 6, Page 2942-2960, November 2025.
PCP‐80% could lessen the pathophysiology of T2DM in terms of controlling blood glucose/lipid levels and enhancing intestinal barrier function, via modulating the intricate web of intestinal microbiota/BAs/BAs signaling pathways. Red vertical arrows denote increases (HPCP‐80% vs. MC), blue vertical arrows indicate decreases (HPCP‐80% vs.

Expression and nucleotide sequence of the Clostridium acetobutylicum β-galactosidase gene cloned in Escherichia coli

, 1991
A gene library for Clostridium acetobutylicum NCIB 2951 was constructed in the broad-host-range cosmid pLAFR1, and cosmids containing the β-galactosidase gene were isolated by direct selection for enzyme activity on X-Gal (5-bromo-4-chloro-3-indoly-β-D ...
