COPOLYMER CONTAINING 3-HYDROXYALKANOATE UNIT AND LACTATE UNIT, AND ITS MANUFACTURING METHOD

Abstract

The present invention relates to a copolymer comprising 3-hydroxyalkanoate monomer unit and lactate monomer unit, or their preparing method. More specifically, the present invention relates to a method for preparing a copolymer comprising lactate monomer and 3-hydroxyalkanoate monomer, wherein the method comprises culturing a cell or plant comprising the gene of enzyme converting lactate and 3-hydroxyalkanoate into lactyl-CoA and 3-hydroxyalkanoyl-CoA, respectively, and polyhydroxyalkanoate synthase gene together, and the copolymer made by the method. The copolymer of the present invention is a biodegradable polymer being able to be usefully used instead of conventional synthetic plastic, and the copolymer can be used also for medical use.
