MUTANTS OF CLOSTRIDIUM BEIJERINCKII THAT ARE BUTANOL HYPER-PRODUCERS

摘要

The present invention relates to mutant strains of Clostridium beijerinckii, particularly produced by chemical mutagenesis of the parent strains C. beijerinckii BA101 and NCIMB 8052. Said mutants can produce more butanol, by means of anaerobic fermentation processes, than the parent strain from which same originate, using different substrates as a carbon source. Therefore, the invention also relates to the use of said mutant strains in methods for producing acetone, butanol and ethanol (ABE) by means of fermentation, and to a method for obtaining said mutant strains.
