Abstract

The invention provides a PHA copolymer including at least a 3-hydroxy-ω-carboxyalkanoic acid represented by a formula (19) or (32) and simultaneously at least a unit represented by a formula (2) or a formula (3) in a molecule, a precursor PHA copolymer having a corresponding vinyl group or a corresponding alkoxycarbonyl group, a biosynthesis method thereof by microorganisms, and a method of producing a desired PHA copolymer from the precursor PHA copolymer: (wherein k, m, n are integers; Rrepresents H, Na, K, R27? represents (A); Rrepresents a substituent on a cyclohexyl group and represents H, CN, NO, a halogen atom, CH, CH, CH, CF, CF, or CF; R includes a residue including a phenyl structure or a thienyl structure; these being independent for each unit).
