Effective isopropanol–butanol (IB) fermentation with high butanol content using a newly isolated Clostridium sp. A1424
BACKGROUND Acetone-butanol-ethanol fermentation has been studied for butanol production. Alternatively, to achieve acetone-free butanol production, use of clostridium strains producing butanol and 1,3-propanediol (1,3-PDO) from glycerol, natural and engineered isopropanol-butanol-ethanol (IBE) producers has been attempted; however, residual 1,3-PDO and acetone, low IBE production by natural IBE...
متن کاملMetabolic flux and transcriptional analysis elucidate higher butanol/acetone ratio feature in ABE extractive fermentation by Clostridium acetobutylicum using cassava substrate
Background: In acetone-butanol-ethanol (ABE) fermentation by Clostridium acetobutylicum ATCC 824 using corn-based substrate, the solvents are generally produced at a ratio of 3:6:1 (A:B:E, w/w). Results: A higher butanol/acetone ratio of 2.9:1 was found when cassava was used as the substrate of an in-situ extractive fermentation by C. acetobutylicum. This ratio had a 64% increment compared to t...
متن کاملRapid and Simultaneous Determination of Acetone, Butanol and Ethanol in Butanol Fermentation Broth by Full Evaporation Headspace Gas Chromatography
A gas chromatography (GC) method including a full evaporation headspace (FE-HS) sampling technique was developed for rapidly and simultaneously measuring volatile products for acetone-butanol-ethanol (ABE) fermentation. In this method, a small volume (<50 μL) of fermentation broth was directly injected into a sealed headspace sample vial (22 mL) and the mass transfer of acetone-butanol-ethanol ...
متن کاملGenome Sequence of Clostridium acetobutylicum GXAS18-1, a Novel Biobutanol Production Strain
Clostridium acetobutylicum is an organism involved in the production of acetone and butanol by traditional acetone-butanol-ethanol fermentation (ABE). We report the draft genome sequence of C. acetobutylicum strain GXAS18-1, which can produce ABE directly from cassava flour.
متن کاملEvaluation of industrial dairy waste (milk dust powder) for acetone-butanol-ethanol production by solventogenic Clostridium species
Readily available inexpensive substrate with high product yield is the key to restoring acetone-butanol-ethanol (ABE) fermentation to economic competitiveness. Lactose-replete cheese whey tends to favor the production of butanol over acetone. In the current study, we investigated the fermentability of milk dust powder with high lactose content, for ABE production by Clostridium acetobutylicum a...
