RECOMBINANT MICROORGANISM FOR PRODUCING POLYLACTIC ACID OR A POLYLACTIC ACID COPOLYMER FROM GLYCEROL AND METHOD FOR PRODUCING POLYLACTIC ACID OR A POLYLACTIC ACID COPOLYMER FROM GLYCEROL USING THE MICROORGANISM

Title:

Document Type and Number:

WIPO Patent Application WO/2011/074842

Kind Code:

A3

Abstract:

The present invention relates to a recombinant microorganism for producing a lactate copolymer or a copolymer using glycerol and to a method for producing a lactate copolymer or a copolymer using glycerol as one of substrates and using the microorganism. According to the present invention, genes of the enzyme which converts lactate into lactile-CoA, and genes of polyhydroxyalkanoate (PHA) synthase which uses lactile-CoA as a substrate are introduced to the microorganism which can use glycerol as a substrate, and the microorganism is then cultured using the glycerol as a substrate to efficiently produce a lactate copolymer and a copolymer.
