摘要： A polyhydroxyalkanoate is disclosed which has in the molecule a unit represented by Chemical Formula (1). wherein R is arbitrarily selected from a hydrogen atom, a halogen atom, CN, NO 2 , COOR', SO 2 R", CH 3 , C 2 H 5 , C 3 H 7 , C(CH 3 ) 2 H and C(CH 3 ) 3 ; where R' is H, Na, K, CH 3 or C 2 H 5 , and R" is OH, ONa, OK, a halogen atom, OCH 3 or OC 2 H 5 ; and x is an integer arbitrarily selected from 1 to 8; with the proviso that a polyhydroxyalkanoate is excluded which has a hydrogen atom as R and x in all the units is 2 or 4. Also disclosed is a process for producing the polyhydroxyalkanoate by the use of a microorganism having the ability to produce the polyhydroxyalkanoate and accumulate it in the bacterial body.

摘要： To provide a novel polyhydroxyalkanoate and a manufacturing method by a microorganism capable of substantially reducing unintended monomer units and obtaining the polyhydroxyalkanoate in a high yield. A microorganism capable of synthesizing a novel polyhydroxyalkanoate having 3-hydroxy-substituted benzoylalkanoic acid as a monomer unit using a substituted benzoylalkanoic acid as a material is cultured in the medium containing a substituted benzoylalkanoic acid, then the polyhydroxyalkanoate produced in the cultured bacteria is extracted and recovered.

摘要： The present invention provides a method of effectively producing polyhydroxyalkanoate having an aromatic substituted residue in its monomer unit. In the method of producing polyhydroxyalkanoate by using microorganisms, microorganisms capable of producing polyhydroxyalkanoate are cultured in a culture medium containing at least one starting compound selected from the group consisting of substituted alkanes represented by formula (1) to produce polyhydroxyalkanoate having, in its molecule, at least one unit selected from the group consisting of 3-hydroxy-substituted alkanoate units represented by formula (2):R―(CH 2 ) n ―CH 2 ―CH 2 ―CH 3 wherein R represents a residue containing a substituted aromatic ring, and n represents any integer of 1 to 8; wherein R represents a residue containing a substituted aromatic ring, and n represents any integer of 1 to 8. In formulas (1) and (2), a residue R is as described in the specification.

摘要： The present invention provides a method for producing highly purified polyhydroxyalkanoate (PHA) with high yield, by removing cell components other than PHA from cells containing PHA. Moreover, the present invention provides a method for simply removing or reducing chlorine remained in the collected PHA particles, when a treatment with an oxidizing agent containing hypochlorite is performed in the production of PHA as described above. One of the above-described methods comprises a step of treating cells containing polyhydroxyalkanoate with an oxidizing agent containing at least hypochlorite, a step of separating the treated cells into a water-soluble fraction and a water-insoluble fraction, and a step of reducing chlorine remained in the water-insoluble fraction. The step of reducing chlorine may be a step of washing the water-insoluble fraction with a hot water, thiosulfate solution or polar solvent solution containing at least an organic polar solvent in which polyhydroxyalkanoate is insoluble.
