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―(CH2)n―CH2―CH2―CH3 (1)
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.
本发明提供了一种有效生产聚羟基烷酸酯的方法,该聚羟基烷酸酯的单体单元中具有芳香取代的残基。在利用微生物生产聚羟基烷酸酯的方法中,将能够生产聚羟基烷酸酯的微生物培养在含有至少一种选自由式(1)表示的取代烷烃组成的组的起始化合物的培养基中,以生产其分子中具有至少一个选自由式(2)表示的3-羟基取代烷酸酯单元组成的组的单元的聚羟基烷酸酯:
R-(CH2)n-CH2-CH2-CH3 (1)
其中 R 代表含有取代芳香环的残基,n 代表 1 至 8 的任意整数;
其中 R 代表含有取代芳香环的残基,n 代表 1 至 8 的任意整数。在式(1)和(2)中,残基 R 如说明书所述。
