The present invention relates to methods of making solvents, such as butanol, acetone or ethanol. In particular, the invention relates to a process for producing a solvent, comprising the step of culturing a solventogenic Clostridium sp. in a culture medium in a culture vessel in the presence of a polysaccharide, wherein the Clostridium sp. is one which is capable of producing a CGTase, and wherein the polysaccharide is one which is a substrate for the CGTase, and harvesting solvent from the culture medium. Preferably, the Clostridium sp. is Clostridium saccharoperbutylacetonicum N1- 4(HMT) or N1-504. The invention also relates to butanol, acetone and ethanol made by such a process. |
