RECOMBINANT MICROORGANISM HAVING A PRODUCING ABILITY OF POLYLACTATE OR ITS COPOLYMERS AND METHOD FOR PREPARING POLYACTATE OR ITS COPOLYMERS USING THE SAME

摘要

Provided are a recombinant microorganism capable of producing polylactate (PLA) or hydroxyalkanoate-lactate copolymers and a method of preparing PLA or hydroxyalkanoate-lactate copolymers using the same. The recombinant microorganism has both a gene encoding a propionyl-CoA transferase from Megasphaera elsdenii and a gene encoding a polyhydroxyalkanoate (PHA) synthase using lactyl-CoA as a substrate. A propionyl-CoA transferase from Megasphaera elsdenii is introduced into the recombinant microorganism to effectively provide lactyl-CoA, thereby enabling efficient preparation of PLA or PLA copolymers.
