Abstract
The present invention relates to recombinant microorganisms having an increased ability to produce butanol, and a method of producing butanol using the same. More specifically, the invention relates to recombinant microorganisms whose ability to produce butanol was increased by manipulation of their metabolic networks, and a method of producing butanol using the same. The recombinant microorganisms having an increased ability to produce butanol comprise a deletion of a gene, which encodes an enzyme that converts acetyl CoA to acetate, in host microorganisms having genes that encode enzymes involved in acetyl CoA and butyryl CoA biosynthetic pathway. The recombinant microorganisms obtained by manipulating the metabolic flux of microorganisms are able to selectively produce butanol with high efficiency, and thus are useful as microorganisms for producing industrial solvents and transportation fuels.
