Acetone, Butanol, and Ethanol (ABE) Production from Food Waste via Clostridium beijerinckii
… economic loss and environmental pollution. Fermentation of food waste to produce acetone, butanol and ethanol (ABE) via fermentation has the potential to valorize food waste by producing value-added chemicals. However, the composition of food wastes from different sources vary, which affects …

Production of 1-butanol and butanol isomers by metabolically engineered Clostridium beijerinckii and Saccharomyces cerevisiae
… chemical that has been produced from the ABE (acetone-butanol-ethanol) fermentation by solventogenic clostridia such as Clostridium beijerinckii. Although the ABE fermentation is considered as a promising process for butanol production, current drawbacks in the ABE fermentation include low …

Nitrogen metabolism and butanol production by South African clostridium beijerinckii and clostridium saccharobutylicum strains
The acetone- butanol-ethanol (ABE) fermentation was one of the first fermentation processes to be industrialized on a large scale, and the dominant product, butanol is particularly significant due to its potential as a modern day fuel additive or fuel extender in the petrochemical industry. A …

Production of Biobutanol from inulin-rich biomass and industrial food processing wastes
… can be produced through acetone-butanol-ethanol (ABE) fermentation from diverse feedstocks. Butanol could occupy a significant portion of advanced biofuel markets if the economics of ABE fermentation process improve. Although, butanol toxicity, low yield, and high butanol recovery costs are some …

Molecular genetic characterization of two solvent pathway dehydrogenases from Clostridium Acetobutylicum
… and a fundamental understanding of the ABE fermentation. The aim of this study was to isolate and characterize genes involved in solventogenesis. The cloning, expression and characterization of the terminal solventogenic butanol dehydrogenase gene ( adhl), and the central pathway …

Genetic Manipulation and Characterization of Solvent-Producing Clostridia
… formulation of a new solventogenic clostridial fermentation medium based on the use of corn steep liquor (CSL). CSL is a by-product of the corn wet-milling industry, and has been used primarily as a feed supplement in the livestock industry. This nutrient-rich medium is an ideal base for use in …

Studies on the regulation of solvent production and endospore formation in Clostridium Acetobutylicum P262
… phase, which characterise the industrial ABE fermentation process were observed in CAMM.

Integrated modeling of bacterial metabolism
… modeling framework for acetone-butanol-ethanol (ABE) fermentation by Clostridium acetobutylicum. ABE fermentation is a biphasic metabolic process during which cells convert carbon sources to organic acids that are later re-assimilated to produce solvents as a strategy for cellular survival. A …

Fermentation studies on Clostridium acetabutylicum
… develop a laboratory system for the study of the ABE fermentation under laboratory conditions. The development of defined and simple laboratory inoculation and build-up procedures for the ABE process was investigated. A defined spore preparation in distilled water gave solvent yields comparable to …

Studies on the sucrose utilization system of Clostridium beijerinckii NCIMB 8052
… in the industrial acetone-butanolethanol (ABE) fermentation during the first half of this century. This fermentation was based predominantly on two substrates: corn mash (rich in starch) and molasses (rich in sucrose). Taxonomically distinct strains were used for ABE fermentations based on …

Combustion quality and regimes for standard and alternative fuels
… production through acetone-butanol-ethanol (ABE) fermentation, ABE, was studied for the first time as a potential alternative fuel in spark ignition (SI) engines. Various blends of ABE and gasoline, with different ratios of acetone, n-butanol, and ethanol were studied under various engine …

Improvement of Biofuel Fermentation Processes With Use of Poly(vinyldodecylimidazolium bromide) for In-situ Product Removal
The production of biofuels through fermentation has become increasingly important due to the need for sustainable energy sources. The fermentation processes of ethanol and n-butanol, by Saccharomyces cerevisiae and Clostridium acetobutylicum, respectively, suffer from end-product inhibition, …

Molecular characterization of three linked genes, fixB, βshbd and adh1 from Clostridium acetobutylicum P262
… various stages of the acetone-butanol-ethanol (ABE) fermentation in C. acetobutylicum P262. Each of the genes produced mRNA transcripts of approximately 1.4 kb. The βhbd and adh1 genes were shown to have at least two major and one minor transcriptional start sites in C. acetobutylicum P262. …

Transcriptomic analyses of Clostridium beijerinckii NCIMB 8052 during transition from acidogenesis to solventogenesis and under butyrate supplemented conditions
… sources. Biobutanol produced through microbial fermentation of biomass has been of great interest because of its various advantages as a biofuel and considerable value as an industrial chemical feedstock. Clostridium beijerinckii is among the prominent species for biobutanol production as it …
