Acetone–butanol–ethanol (ABE) fermentation in an immobilized cell trickle bed reactor
Biotechnology and Bioengineering, 1989AbstractAcetone–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.

Maximizing the production of butyric acid from food waste as a precursor for ABE-fermentation
Science of The Total Environment, 2017The current study reports on the maximization of butyric acid production from food waste using a mixed microbial fermentation. In semi-continuous fermentations the effect of three different pH values (5.5, 7.0 and 9.0), three different temperatures (37°C, 55°C and 70°C) and two levels of hydraulic retention time (HRT, 2days and 6days) on the formation ...

Multi-Objective Optimization of an ABE Fermentation System for Butanol Production as Biofuel
International Journal of Chemical Reactor Engineering, 2019Abstract In this work, a previously reported unstructured kinetic model of Clostridium acetobutylicum ATCC 824, validated with experimental data under different culture conditions, was used to determine the optimal process conditions from an ABE fermentation system for ...

Bacteriophage infections in the industrial acetone butanol (AB) fermentation process.
Journal of molecular microbiology and biotechnology, 2000The 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 ...

Multi-objective Optimization of Butanol Production During ABE Fermentation
2013Liquid biofuels produced from biomass have the potential to partly replace gasoline. One of the most promising biofuels is butanol which is produced in acetone-butanol-ethanol (ABE) fermentation. The ABE fermentation is characterized by its low butanol concentration in the final fermentation broth.

Experiments were performed to determine the cause of "acid crash", a phenomenon which occasionally occurs in pH-uncontrolled batch fermentations resulting in premature cessation of ABE (acetone butanol) production. The results indicate that "acid crash" occurs when the concentration of undissociated acids in the broth exceeds 57 - 60 mmol/l. Prevention
