ABSTRACT:
The present invention is directed to a copolymer containing a unit represented by Formula (1): ##STR1## wherein Y represents a hydrocarbon residue having 1 to 13 carbon atoms which may have 1 to 4 double bonds. A method for production thereof comprises the steps of culturing microorganisms of the genus Pseudomonas under limitation of nutrients other than carbon sources using a medium containing long-chain fatty acids having 14 to 22 carbon atoms or lower alcohol esters thereof, or triglycerides comprising long-chain fatty acids having 14 to 22 carbon atoms as carbon sources; washing the bacterial cells after completion of cultivation; extracting the bacterial cells; and recovering a polyester from the extracts.
