    摘要： A method for preparing a pitch for carbon fibers and a pitch for carbon fibers prepared by the same are disclosed. The method includes introducing a peroxide compound and ozone into a petroleum-process residual oil, followed by heat treatment for reaction. By the method, the pitch for carbon fibers, which exhibits excellent oxidative stabilization and oxidative incompatibility while having a high softening point and high strength, can be obtained at high yield at a relatively low temperature.

    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 a recombinant microorganism having an enhanced ability to produce ethanol and butanol and a method for preparing ethanol and butanol using the same, and more particularly to a recombinant microorganism having an enhanced ability to produce ethanol and butanol, into which a gene encoding CoA transferase and a gene encoding alcohol/aldehyde dehydrogenase are introduced, and to a method for preparing ethanol and butanol using the same. The recombinant microorganism according to the present invention, obtained by manipulating metabolic pathways of microorganisms, is capable of producing butanol and ethanol exclusively without producing any byproduct, and thus is useful as a microorganism producing industrial solvents and transportation fuel.
