    摘要: The present invention is related to a method for improving a strain on the basis of in silico analysis, in which it compares the genomic information of a target strain for producing a useful substance to the genomic information of a strain overproducing the useful substance so as to primarily screen genes unnecessary for the overproduction of the useful substance, and then to secondarily screen genes to be deleted through performing simulation with metabolic flux analysis. According to the present invention, an improved strain can be effectively constructed by the metabolic and genetic engineering approach comprising comparatively analyzing the genomic information of a target strain for producing a useful substance and the genomic information of a strain producing a large amount of the useful substance to screen candidate genes and performing in silico simulation on the screened candidate genes to select a combination of genes to be deleted, which shows an improvement in the production of the useful substance. Accordingly, the time, effort and cost required for an actual wet test can be significantly reduced.

    摘要: Provided are novel rumen bacterial mutants resulted from the disruption of a lactate dehydrogenase gene (ldhA) and a pyruvate formate-lyase gene (pfl) from rumen bacteria; a novel bacterial mutant (Mannheimia sp. LPK7) having disruptions of a ldhA, a pfl,a phosphotransacetylase gene (pta), and a acetate kinase gene (ackA); a novel bacterial mutant (Mannheimia sp. LPK4) having disruptions of a ldhA, a pfl, and a phosphoenolpyruvate carboxylase gene (ppc) involved in the immobilization of CO2 in a metabolic pathway of producing succinic acid; and a method for producing succinic acid, characterized by culture of the above mutants in anaerobic conditions. The bacterial mutants have the property of producing succinic acid at high concentration while producing little or no organic acids, as compared to the prior wild-type strains of producing various organic acids. Thus, the bacterial mutants are useful as strains for the industrial production of succinic acid.

    摘要: A method for producing target proteins by deleting or amplifying ibpA and/or ibpB genes coding for inclusion body-associated proteins. Two methods for producing target proteins using ibpA and/or ibpB genes coding for inclusion body-associated proteins of E. coli are described. The first method enhances the secretory production and activity of target proteins using ibpA and/or ibpB genes-deleted bacteria. The second method enhances the production of target proteins in the cytoplasm and also converts the target proteins from soluble form to insoluble inclusion body, using ibpA and/or ibpB gene-amplified bacteria.

    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.
