Pentose Metabolism in Clostridium acetobutylicum

Agricultural and Biological Chemistry, 1969
L-Arabinose ketol-isomerase (EC 5. 3. 1. 4) was extracted from the L-arabinose-grown cells of Clostridium acetobutylicum and partially purified by ammonium sulfate fractionation, DEAE-cellulose column chromatography and the gel filtration on Sephadex G-200. Optimum pH and temperature for the activity of the enzyme were 7.5 and 37°C, respectively.

Microbial Conversion of Glycerol Into 1,3‐Propanediol by Fermentation: Review of Fundamentals and Operational Strategies

Microbial Biotechnology, Volume 18, Issue 11, November 2025.
This review highlights recent advances in microbial fermentation strategies for converting glycerol, a biodiesel by‐product, into 1,3‐propanediol. It discusses metabolic pathways, microbial inocula and key operational parameters to optimise production, supporting sustainable chemical synthesis aligned with circular economy principles. ABSTRACT Over the

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.

A Quantitative System-Scale Characterization of the Metabolism of Clostridium acetobutylicum

mBio, 2015
Engineering industrial microorganisms for ambitious applications, for example, the production of second-generation biofuels such as butanol, is impeded by a lack of knowledge of primary metabolism and its regulation.

Genome-Wide TSS Distribution in Three Related Clostridia with Normalized Capp-Switch Sequencing

Microbiology Spectrum, 2022
Transcription initiation is a tightly regulated process that is crucial for many aspects of prokaryotic physiology. High-throughput transcription start site (TSS) mapping can shed light on global and local regulation of transcription initiation, which in

Characterization of the thermophilic xylanase Fsa02490Xyn from the hyperthermophile Fervidibacter sacchari belonging to glycoside hydrolase family 10

FEBS Open Bio, Volume 15, Issue 10, Page 1629-1642, October 2025.
Fervidibacter sacchari is a member of the bacterial phylum Armatimonadota, only a few of which have been cultivated. It is a hyperthermophilic polysaccharide degradation specialist. We show that a secreted enzyme, Fsa02490Xyn, is an endoxylanase belonging to glycoside hydrolase family 10.

Redox-switch regulatory mechanism of thiolase from Clostridium acetobutylicum [PDF]

, 2015
Thiolase is the first enzyme catalysing the condensation of two acetyl-coenzyme A (CoA) molecules to form acetoacetyl-CoA in a dedicated pathway towards the biosynthesis of n-butanol, an important solvent and biofuel.

A single residue affects the dynamics and shape of a tetrameric GH43 β‐1,4‐d‐xylosidase from Levilactobacillus brevis DSM1269

Protein Science, Volume 34, Issue 10, October 2025.
Abstract Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus.
