Bio-butanol has become another solution for the alternative to gasoline fuel. Its better characteristics of higher energy content, less hydroscopic and volatile which make it possible to use pre-existing transport infrastructure, than ethanol is regaining the reputation of conventional
ABE (Acetone-Butanol-Ethanol) fermentation. However, the potent toxicity of butanol on the main ABE producers derived from Clostridium acetobutylicum ATCC 824, Clostridium beijerinckii NCIMB 8052, Clostridium saccharoperbutylacetonicum N1-4 etc., is still a major obstacle for economic production as a fuel. Extensive studies have been done only to reach the best titer around 20 g/L. For the production of n-butanol, we have constructed several recombinant C. beijerinckii strains by introducing E.coli-Clostiridum shuttle vecor. In this presentation,
the detailed results will be presented.
