Production of butanol from glycerol by using Clostridium pasteurianum MBEL_GLY2 |
| 초록 |
In the present work, studies related to butanol production by glycerol fermentation were undertaken. Chemical mutagenesis of C. pasteurianum cells were performed to obtain a hyper butanol producing mutant strain MBEL_GLY2. Corresponding average butanol yield was found to be 0.30 g/g. The maximum butanol productivity obtained during present study was found to be 0.43 g/l/h. Acetone, acetate and butyrate were not detected in the fermentation broth while ethanol was produced in trace quantities. PDO was never produced as major product. An average of 27.4 g/l total solvent (Butanol, Ethanol and PDO) was produced under optimized conditions. A maximum butanol selectivity of 0.65 g butanol per g of total solvent was obtained.
