The bottleneck issue in both current and future biofuel production platforms is economic viability. The implementation of biorefineries could be applied as a potential solution for this problem. Glycerol rich streams are generated as waste product during biodiesel and bioethanol production. Development of glycerol based fermentation process can highly improve the economic viability of biofuel industry. In the present work, studies related to bio butanol production by glycerol fermentation were undertaken. Chemical mutagenesis of C.pasteurianum cells were performed to obtain a hyper butanol producing mutant strainMBEL_GLY2. Under the optimized condition of operational parameters ,MBEL_GLY2 strain could produce an average of1 7.8±0.32g/l butanol. Corresponding average butanol yield was found to be 0.30±0.01g/g. The maximum butanol productivity obtained during present study was found to be 0.43±0.04g/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±0.27g/l total solvent(Butanol, Ethanol and PDO) was produced under optimized conditions. A maximum butanol selectivity of 0.65±0.02g butanol per g of total solvent was obtained. These are the highest reported results so far, in terms of butanol titer, yield, productivity and selectivity, obtained by batch fermentation of glycerol using C.pasteurianum.
