Butanol is a promising biofuel that have superior characteristics over ethanol. It is produced by several clostridial species through the so-called acetone-butanol-ethanol fermentation. However, acetone itself is not suitable for current engines. In addition, butanol has slightly lower octane rate when compared to commercial gasoline fuel. In this study, we introduced a primary/secondary alcohol dehydrogenase gene into two hosts, Clostridium acetobutylicum ATCC 824 and C. beijerinckii NCIMB 8052. Even this gene worked well in both hosts, conversion of acetone into isopropanol slightly reduce butanol yield possibly due to additional consumption of reducing equivalents for acetone reduction.
