    摘要: In a method and a system for decolorizing and deodorizing a polyhydric alcohol according to embodiments of the present invention, a mixture liquid containing a first polyhydric alcohol obtained by a separation process is prepared. The mixture liquid is subjected to a distillation treatment to preliminarily remove substances with different colors and odors to generate a pre-treatment liquid. The pre-treatment liquid is subjected to an adsorption treatment. Through a combination of the distillation treatment and the adsorption treatment, the removing efficiency of the substances with different colors and odors can be increased.

    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.
