Production of solvents (ABE fermentation) from whey permeate by continuous fermentation in a membrane bioreactor

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.

Biobutanol production from sustainable biomass process of anaerobic ABE fermentation for industrial applications

Archives of Microbiology, 2022
The growing population increases the need to develop advanced biological methods for utilizing renewable and sustainable resources to produce environmentally friendly biofuels. Currently, energy resources are limited for global demand and are constantly depleting and creating environmental problems. Some higher chain alcohols, like butanol and ethanol,

Electron receptor addition enhances butanol synthesis in ABE fermentation by Clostridium acetobutylicum

Bioresource Technology, 2018
The techniques for enhancing butanol production in ABE fermentation by Clostridium acetobutylicum generally focus on adding electron carrier to strengthen NADH synthesis, repressing hydrogenase by aerating CO, supplementing butyrate, etc. However, those methods suffer from the problems of total solvent decrease, high purification cost, using expensive ...

Acetone-Butanol-Ethanol (ABE) Fermentation Wastewater Treatment by Oleaginous Yeast Trichosporon cutaneum

Applied Biochemistry and Biotechnology, 2015
In the present study, acetone-butanol-ethanol (ABE) fermentation wastewater with high chemical oxygen demand (COD) value (about 18,000 mg/L) was biologically treated by oleaginous yeast Trichosporon cutaneum without any pretreatment. During fermentation, most COD degradation was finished within 48 h and finally, a maximum COD degradation of 68% was ...

Acetone–butanol–ethanol (ABE) fermentation in an immobilized cell trickle bed reactor

Biotechnology and Bioengineering, 1989
AbstractAcetone–butanol–ethanol (ABE) fermentation was successfully carried out in an immobilized cell trickle bed reactor. The reactor was composed of two serial columns packed with Clostridium acetobutylicum ATCC 824 entrapped on the surface of natural sponge segments at a cell loading in the range of 2.03–5.56 g dry cells/g sponge.

Carbon footprint of biobutanol by ABE fermentation from corn and sugarcane

Renewable Energy, 2016
This 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.

Sorption‐assisted thermopervaporation method for organics recovery from ABE fermentation broth

Journal of Chemical Technology & Biotechnology, 2019
AbstractBACKGROUNDFermentation broth is a complex mixture which contains target and other organic compounds which must be continuously recovered to maintain microorganism activity. To overcome this problem, a sorption‐assisted thermopervaporation (SA‐TPV) method has been proposed, which enables the removal of volatile organics by means of evaporation ...

Enhanced Down-Stream Processing of Biobutanol in the ABE Fermentation Process

2016
Butanol 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.

Lumping kinetics of ABE fermentation wastewater treatment by oleaginous yeastTrichosporon cutaneum

Preparative Biochemistry & Biotechnology, 2017
Lumping kinetics models were built for the biological treatment of acetone-butanol-ethanol (ABE) fermentation wastewater by oleaginous yeast Trichosporon cutaneum with different fermentation temperatures. Compared with high temperature (33°C, 306 K) and low temperature (23°C, 296 K), medium temperature (28°C, 301 K) was beneficial for the cell growth ...

Bacteriophage infections in the industrial acetone butanol (AB) fermentation process.

Journal of molecular microbiology and biotechnology, 2000
The reported incidence and effects of bacteriophage infections occurring in the industrial acetone butanol (AB) fermentation processes operated in the USA, Japan, and Puerto Rico during the earlier part of the twentieth century is reviewed. The growth characteristics and solvent-producing ability of a lysogenic strain of Clostridium madisonii isolated ...
