    摘要: 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.

    摘要: The present invention relates to mutant microorganisms having improved productivity of branched-chain amino acids, and a method for producing branched-chain amino acids using the mutant microorganisms. More specifically, relates to mutant microorganisms having improved productivity of L-valine, which are produced by attenuating or deleting a gene encoding an enzyme involved in L-isoleucine biosynthesis, a gene encoding an enzyme involved in L-leucine, and a gene encoding an enzyme involved in D-pantothenic acid biosynthesis, and mutating a gene encoding an enzyme involved in L-valine biosynthesis, such that the expression thereof is increased, as well as a method for producing L-valine using the mutant microorganisms. The inventive mutant microorganisms produced by site- specific mutagenesis and metabolic pathway engineering can produce branched-chain amino acids, particularly L-valine, with high efficiency, and thus will be useful as industrial microorganisms for producing L-valine.
