Pyruvate fermentation by Clostridium acetobutylicum

Biochemistry and Cell Biology, 1989
Clostridium acetobutylicum ATCC 824 using pyruvate as the sole carbon source produced mainly acetate and butyrate as end products of fermentation. Acetate and butyrate kinase activities were higher in cells growing in the presence of pyruvate than glucose, whereas the level of the acetoacetate decarboxylase, an enzyme involved in solvent formation ...

Transcriptomic studies of solventogenic clostridia, Clostridium acetobutylicum and Clostridium beijerinckii

Biotechnology Advances, 2022
Solventogenic clostridia are not a strictly defined group within the genus Clostridium but its representatives share some common features, i.e. they are anaerobic, non-pathogenic, non-toxinogenic and endospore forming bacteria. Their main metabolite is typically 1-butanol but depending on species and culture conditions, they can form other metabolites ...

Effects of Acetic and Formic Acid on ABE Production by Clostridium acetobutylicum and Clostridium beijerinckii

Biotechnology and Bioprocess Engineering, 2012
The effect of acetic acid and formic acid on acetone-butanol-ethanol (ABE) production by solventogenic Clostridia was investigated. The ABE concentration in Clostridium acetobutylicum was found to have increased slightly on addition of 3.7 similar to 9.7

Engineering Cellulase Activity into Clostridium acetobutylicum

2012
Clostridium acetobutylicum produces substantial amounts of butanol, and an engineered cellulolytic strain of the bacterium would be an attractive candidate for biofuel production using consolidated bioprocessing. Recent studies have shown that this solventogenic bacterium can be used as a host for heterologous production and secretion of individual ...

Fluoreszenzproteine in Clostridium acetobutylicum

2013
Derzeit gibt es nur wenige molekulare Werkzeuge, um die Genexpression biotechnologisch relevanter Clostridien gezielt zu modifizieren. Daher wurde in dieser Arbeit für den anaeroben Modellorganismus C. acetobutylicum ein neues Fluoreszenz-basiertes In-vivo-Reportersystem etabliert.

Fermentation of xylan by Clostridium acetobutylicum

Enzyme and Microbial Technology, 1986
Abstract The ability of Clostridium acetobutylicum to utilize hemicelluloses as a substrate for butanol production was examined. Direct fermentation of byproduct corn fibres from the wet milling process showed complete utilization of starch and 20% utilization of hemicellulose with concurrent production of solvents and organic acids. Fermentations of

Butyrate as a growth factor of Clostridium acetobutylicum

Metabolic Engineering
Abstract The butyrate biosynthetic pathway not only contributes to electron management and energy generation in butyrate forming bacteria, but also confers evolutionary advantages to the host by inhibiting the growth of surrounding butyrate-sensitive microbes.

Production of Biobutanol by Clostridium Acetobutylicum

2009
The socio-economic scenario of the third millennium revives the interest in production of biofuel for transport purposes by fermentation processes and the butanol appears to be a promising candidate. Present contribution reports about results of a research activity aiming at investigating the feasibility of the acetone-butanol-ethanol (ABE) production ...

Vectors for Use in Clostridium acetobutylicum

1993
In the last two decades, interest in using surplus/waste biomass in biocatalytic processes to produce chemicals and fuels of high added value, as an alternative to chemical synthesis from petroleum feedstocks, has exhibited considerable fluctuation. The underlying argument for such developments seems irrefutable. Fossil fuels are a finite resource.

The Ferredoxin-dependent Reduction of Chloramphenicol by Clostridium acetobutylicum

Journal of General Microbiology, 1971
SUMMARY: Chloramphenicol did not inhibit growth and protein synthesis when added (100 μg./ml.) to growing cultures of Clostridium acetobutylicum, even though the organism was sensitive to this antibiotic in plate assay. This paradox was explained by the finding that chloramphenicol was rapidly reduced and thus detoxified by actively growing cultures ...
