  • Method of manufacturing glycerol carbonate
    Patent number: 8314259
    Abstract: Disclosed is a method of manufacturing a glycerol carbonate (GC). The method includes a bio-catalyst reaction for generating the GC and byproducts generated by reacting a reactant solution using a lipase of a bio-catalyst. In this instance, the reactant solution is prepared by adding glycerol, a glycerol-containing composition, or a dimethyl carbonate (DMC) in a reaction solvent.
    Type: Grant

  • ENHANCED ETHANOL AND BUTANOL PRODUCING MICROORGANISMS AND METHOD FOR PREPARING ETHANOL AND BUTANOL USING THE SAME
    Publication number: 20110027845
    Abstract: 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.
