    • PURPOSE: Provided is a novel polyhydroxyalkanoate (hereinafter, sometimes abbreviated to "PHA"). Further, a method for high efficient production of PHA using microorganisms having an ability of producing PHA and accumulating it in their cells is provided. CONSTITUTION: 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. The polyhydroxyalkanoate has a monomer unit composition represented by the following formula(1) of AxB(1-x), wherein A is at least one monomer unit represented by the following chemical formula(2), where n is an integer of 1 to 8; and B is at least one selected from monomer units represented by the following chemical formula(3), where p is an integer of 0 to 10, and monomer units represented by the following chemical formula(4): where q is 3 or 5; and x is not less than 0.01 and less than 1.
    • 目的:提供新的聚羟基链烷酸酯(以下有时缩写为“PHA”)。 此外,提供了使用具有产生PHA并将其积聚在其细胞中的能力的微生物高效生产PHA的方法。 构成:在含有苯甲酰基链烷酸和糖类的培养基中培养能够利用苯甲酰基链烷酸作为起始原料生产具有3-羟基苯甲酰基链烷酸作为单体单元的新型聚链烷酸酯的微生物,提取并回收培养细胞中产生的聚羟基链烷酸酯。 聚羟基链烷酸酯具有由AxB(1-x)所示的下式(1)表示的单体单元组成,其中A为至少一个由下列化学式(2)表示的单体单元,其中n为1至8的整数 ; 和B是选自下列化学式(3)表示的单体单元中的至少一种,其中p为0〜10的整数,以及由下列化学式(4)表示的单体单元:其中q为3或5; x不小于0.01且小于1。
