RECOMBINANT RALSTONIA EUTROPHA CAPABLE OF PRODUCING POLYLACTIC ACID OR POLYLACTIC ACID COPOLYMER, AND METHOD FOR PRODUCING POLYLACTIC ACID OR POLYLACTIC ACID COPOLYMER USING SAME

摘要

Provided are a recombinant Ralstonia eutropha capable of producing polylactate or a hydroxyalkanoate-lactate copolymer, and a method of preparing polylactate or a hydroxyalkanoate-lactate copolymer using the same. The recombinant Ralstonia eutropha, which is prepared by introducing a gene of an enzyme converting lactate into lactyl-CoA and a gene of a polyhydroxyalkanoate (PHA) synthase using lactyl-CoA as a substrate thereto, may be cultured, thereby efficiently preparing a lactate polymer and a lactate copolymer.
