Patent ID: 8703449

Claim:
A method of producing a glycolic acid-containing polyhydroxyalkanoate polymer comprising Providing a feedstock comprising glycolic acid, 1,4-butane dial, 4-hydroxybutyric acid, or combinations thereof to bacteria expressing a polyhydroxyalkanoate (PHA) synthase and at least one enzyme selected from the group consisting of acetoacetyl-CoA reductases and beta-ketoacyl-CoA thiolases and at least one enzyme for the production of glycolyl-CoA selected from the group consisting of aldehyde dehydrogenase, diol oxidoreductase, enoyl-CoA dehydrase, beta acyl-CoA dehydrogenase, thiolases, and acyl-CoA transferase, to produce the glycolic acid-containing polyhydroxyalkanoate polymer.
