POLYHYDROXYALKANOATE POLYESTER HAVING VINYL PHENYL STRUCTURE IN THE SIDE CHAIN AND PRODUCTION METHOD THEREOF

摘要

PURPOSE: Provided are a polyhydroxyalkanoate (PHA) type that comprises a 3-hydroxy- omega -(4-vinylphenyl)alkanoic acid unit and a production method of such a PHA utilizing a microorganism that can produce the PHA using omega -(4-vinylphenyl)alkanoic acid as a raw material. CONSTITUTION: The polyhydroxyalkanoate type polyester comprises one unit % or more of 3-hydroxy- omega -(4-vinylphenyl)alkanoic acid unit represented by chemical formula(1), where n is one or more integers arbitrarily selected from 0 to 7. The method of producing a polyester comprises the steps of: (1) providing omega -(4-vinylphenyl)alkanoic acid represented by chemical formula(4) as a raw material, where p is one or more integers arbitrarily selected from 0 to 7; and (2) producing a polyester comprising one unit % or more of 3-hydroxy- omega -(4-vinylphenyl)alkanoic acid unit represented by chemical formula(1) by using a microorganism capable of producing the polyester from the omega -(4-vinylphenyl)alkanoic acid.
