A microbial polyhydroxyalkanoate which comprises one or more of monomer units represented by Formula (1),
where R is at least one selected from the group represented by any one of Formulas (2), (3) and (4);
in Formula (2), R1 is selected from the group consisting of hydrogen atom (H), halogen atom, —CN, —NO2, —CF3, —C2F5 and —C3F7, and q is an integer of 1 to 8;
in Formula (3), R2 is selected from the group consisting of hydrogen atom (H), halogen atom, —CN, —NO2, —CF3, —C2F5 and —C3F7, and r is an integer of 1 to 8;
in Formula (4), R3 is selected from the group consisting of hydrogen atom (H), halogen atom, —CN, —NO2, —CF3, —C2F5 and —C3F7, and s is an integer of 1 to 8. The production method is also disclosed.
