碩士 === 國立中央大學 === 化學工程與材料工程學系 === 101 === In this research, the hydrophobic ionic liquid, [Hmim][PF6] was applied to the extractive fermentation of Clostridium acetobutylicum to remove butanol from the broth. The toxic ionic liquid remained in the broth was adsorbed by activated carbon. During the extraction operation, 2.2 g/L of butanol was removed from the broth. The production of butanol was stopped after the extraction due to the toxicity of residual ionic liquid. C. acetobutylicum cannot grow in the medium which had contact with the ionic liquid. After adsorption by 1 : 10 (w/v) activated carbon for 5 minutes, the production of butanol by C. acetobutylicum can reach 70% of the amount of control experiment . The fermentation after extraction and adsorption can remove 2.99 g/L of butanol in the broth. But the butanol production cannot be enhanced by current operation conditions. It means that more operation conditions should be discussed to find the optimal way to improve the butanol production.
