ポリ乳酸またはポリ乳酸共重合体生成能を有する組換えラルストニアユートロファ及びこれを利用してポリ乳酸またはポリ乳酸共重合体を製造する方法

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.
