NOVEL COPOLYMER OF [POLY(MCL 3-HYDROXYALKANOATE-CO-LACTATE)] AND METHOD FOR PREPARING THE SAME

摘要

A medium-chain-length 3-hydroxyalkanoate-lactate copolymer is provided to replace uses of the conventional synthetic plastics and to be applicable to medical fields. A medium-chain-length 3-hydroxyalkanoate-lactate copolymer contains lactate and 3-hydroxyalkanoate of medium chain length as repeating units. The 3-hydroxyalkanoate of medium chain length is selected from the group comprising 3-hydroxyhexanoate, 3-hydroxyheptanoate, 3-hydroxyoctanoate, 3-hydrononanoate, 3-hydroxydecanoate, 3-hydroxyundecanoate, and 3-hydroxydodecanoate. A method for preparing the copolymer includes a step of culturing or cultivating a cell or plant having a gene of an enzyme that coverts lactate into lactyl-CoA and 3-hydroxyalkanoate into 3-hydroxyalkanoyl-CoA, and a polyhydroxyalkanoate synthase gene.
