|Abstract:||A unique Clostridium species strain G117 was obtained in this study to be capable of producing dominant butanol from glucose. Butanol of 13.50. g/L was produced when culture G117 was fed with 60. g/L glucose, which is ~20% higher than previously reported butanol production by wild-type Clostridium acetobutylicum ATCC 824 under similar conditions. Strain G117 also distinguishes itself by generating negligible amount of ethanol, but producing butanol and acetone as biosolvent end-products. A butanol dehydrogenase gene (bdh gene) was identified in strain G117, which demonstrated a ~200-fold increase in transcription level measured by quantitative real-time PCR after 10. h of culture growth. The high transcription suggests that this bdh gene could be a putative gene involved in butanol production. In all, Clostridium sp. strain G117 serves as a potential candidate for industrial biobutanol production while the absence of ethanol ensures an economic-efficient separation and purification of butanol. © 2012 Elsevier Ltd.|
