Abstract: Biobutanol generation from lignocellulosic biomass is impeded by low butanol concentration in the fermentation broth and high costs associated with pre-processing of raw materials. In this doctorial thesis, novel solventogenic Clostridium strains were identified and further being investigated to improve the economic viability of biobutanol production. The wide-type Clostridium sp. strain BOH3 shows superior capability of fermenting 75.2 g/L glucose to produce 18.7 g/L butanol, and producing 5.15 g/L butanol from un-detoxified horticultural waste hydrolysate. Clostridium sp. strain G117 distinguished itself by capable of using xylan as the sole carbon source to produce 1.24 g/L butanol. Results from this study lay a foundation to the industrial-scale cost-effective biological butanol production.
