Abstract
The present invention provides the use of acid pretreated biomass such as jatropha seed cake, pongamia seed cake and banana stems as renewable feedstock for butanol production by the mutant Clostridium acetobutylicum MTCC 587. Chemical mutagenesis was carried out for improvement of the strain for better butanol tolerance and production. This present invention for the first time has reported an efficient process for high yield of butanol obtained in single batch fermentation using acid pretreated jatropha seed cake.

A culture of a mutant strain of C. acetobutylicum, MTCC 5587 which has increased tolerance to butanol as compared to its wild strain.
A process of obtaining a mutant strain of C. acetobutylicum, MTCC 5587 by chemical mutagenesis of C. acetobutylicum ATCC 9259.
A process of production of high yield of butanol from pretreated biomass using mutant strain of C. acetobutylicum, MTCC 5587 with enhanced butanol tolerance, which comprises fermentation of pre-treated biomass in the presence of a nutrient medium.
