Effect of inoculum and nutrient medium composition on butanol production by Clostridium acetobutylicum
Nutrient medium composition was defined for production of the active starter cultures of bacteria Clostridium acetobutylicum - butanol producers. Comparative investigations were performed to analyze solventogenic activity of the strain on media with food-processing wastes as main carbon source. Completed studies demonstrated that a promising substrate for biobutanol production is corn cake hydrolizate. Selected balanced combination of rye flour medium and corn cake hydrolizate ensured less costly conventional process of acetone-butanol fermentation and did not affect its productivity.
