ENHANCED BUTANOL PRODUCING MICROORGANISMS AND METHOD FOR PREPARING BUTANOL USING THE SAME

摘要

The present invention relates to a recombinant mutant microorganism having enhanced butanol producing capacity and a method for producing butanol using the same. In the microorganism, genes coding for enzymes responsible for the biosynthesis of lactate, ethanol and/or acetate are deleted or attenuated and genes coding for enzymes involved in butanol biosynthesis are introduced and amplified.
