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 ...

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 ...

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.

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 ...

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
