Continuous acetone-ethanol-butanol fermentation by immobilized cells of Clostridium acetobutylicum



Continuous acetone-ethanol-butanol fermentation by immobilized cells of Clostridium acetobutylicum



Biomass and Bioenergy 20(2): 119-132



Eight Clostridium acetobutylicum strains were examined for alpha -amylase and strains B-591, B-594 and P-262 had the highest activities. Defibered sweet potato slurry (DSPS), containing 39.7 g starch litre-1, supplemented with potassium phosphate (1.0 g litre-1), cysteine-HCl (5.0 g litre-1), the antifoam (polypropylene glycol, 0.1 mg ml-1), was used as continuous feedstock (FS) to a multistage bioreactor system for acetone-ethanol-butanol (AEB) fermentation.
