Changes in efflux pump activity of Clostridium beijerinckii throughout ABE fermentation
Applied Microbiology and Biotechnology, 2021Pumping toxic substances through a cytoplasmic membrane by protein transporters known as efflux pumps represents one bacterial mechanism involved in the stress response to the presence of toxic compounds. The active efflux might also take part in exporting low-molecular-weight alcohols produced by intrinsic cell metabolism; in the case of solventogenic

Investigation of acetone-butanol-ethanol (ABE) fermentation by fluorescence
Journal of Fluorescence, 1994Photophysical techniques have potential for the development of optical sensors in monitoring and controlling fermentors. In the particular case of acetone-butanol-ethanol (ABE) fermentation, carried out by bacteria of the speciesClostridium acetobutylicum, we have developed two studies based on fluorescence spectroscopy.

ABE fermentation products recovery methods—A review
Renewable and Sustainable Energy Reviews, 2015Abstract Butanol has a great potential as a biofuel and to date a lot of research has been done both in terms of more efficient butanol production as well as in developing product recovery methods. Many of them deal with separation techniques which can be used for selective recovery of acetone, n-butanol and ethanol from model solutions and ...

Application of novel technology to the abe fermentation process
Applied Biochemistry and Biotechnology, 1992Traditional technology for ABE production and recovery does not allow an economic process. However, use of a fluidized-bed reactor using immobilized cells in a continuous fermentation process, coupled with product removal and concentration by a membrane process, is a viable option.

Pervaporative stripping of acetone, butanol and ethanol to improve ABE fermentation
Bioseparation, 2000Acetone-butanol-ethanol fermentation by anaerobic bacterium C. acetobutylicum is a potential source for feedstock chemicals. The problem of product induced inhibition makes this fermentation economically infeasible. Pervaporation is studied as an effective separation technique to remove the toxic inhibitory products.

ABE Fermentation From Enzymatic Hydrolysate of NaOH-Pretreated Corncobs
Biomass and Bioenergy, 2014Abstract Acetone butanol ethanol (ABE) was produced from enzymatic-hydrolyzed corncobs by Clostridium saccharobutylicum DSM 13864. Pretreatment of corncobs was carried out with 0.5 mol L−1 NaOH followed by enzymatic hydrolysis. The yield of total reducing sugars was 917 g kg−1 pretreated (de-lignified) and washed corncobs.

Bioprocess Engineering, 1989
A continuous bioreactor where cells were recycled using a cross-flow microfiltration (CFM) membrane plant was investigated for the production of solvents (ABE fermentation) from whey permeate using Clostridium acetobutylicum P262. A tubular CFM membrane plant capable of being backflushed was used.

Carbon footprint of biobutanol by ABE fermentation from corn and sugarcane
Renewable Energy, 2016This article focuses on the saving potential of butanol as regards greenhouse gas (GHG) emissions. It is known that butanol can be used as a biofuel to decrease the greenhouse gas emissions from transport and that butanol may overcome blend wall limitations better than ethanol. However, the GHG emissions of butanol are not well known.

Enhanced Down-Stream Processing of Biobutanol in the ABE Fermentation Process
2016Butanol is considered a superior biofuel, as it is more energy dense and less hygroscopic than bioethanol, resulting in higher possible blending ratios with gasoline. However, the production cost of the acetone-butanol-ethanol (ABE) fermentation process is high, mainly due to the low butanol titer, yield, and productivity in bioprocesses.
