ABSTRACT:
Microorganisms capable of producing novel polyalkanoates having 3-hydroxybenzoylalkanoic acids as monomer units by utilizing benzoylalkanoic acids as starting materials are cultured in media containing benzoylalkanoic acids and saccharides, and the polyhydroxyalkanoates produced in the culture cells are extracted and recovered.
