摘要：

An extractive fermentation system was developed to prevent end-product inhibition of Clostridium acetobutylicum IAM 19012, which mainly produces butanol and acetone. Butanol exhibited greater toxicity to the microorganism than acetone, and its growth was completely inhibited above 10 kg/m**3 of butanol. As an extracting solvent suitable for acetone-butanol fermentation, oleyl alcohol (cis-9-octadecen-1-ol) and C-20 guerbet alcohol (branched-chain alcohol of carbon number, 20) were selected from among 29 organic compounds, based on their nontoxicity to the microorganism. These two solvents had high partition coefficients for butanol, and could be reused without deterioration.
