Title:

METHOD FOR CONTROLLING MOLECULAR WEIGHT OF POLYHYDROXYALKANOATE IN WHICH UNITS CONTAINING PHENYL, THIENYL OR CYCLOHEXYL STRUCTURE-HAVING RESIDUES IN SIDE CHAINS ARE CONTAINED, AND POLYHYDROXYALKANOATE

Document Type and Number:

Japanese Patent JP2003319792

Kind Code:

A

Abstract:

To provide a method for controlling the molecular weight of a polyhydroxyalkanoate in which units containing phenyl, thienyl or cyclohexyl structure-having residues in side chains are contained, and to provide the polyhydroxyalkanoate having a controlled molecular weight.

This method for controlling the molecular weight of the polyhydroxyalkanoate is characterized by having a process for culturing a microorganism having an ability for producing the polyhydroxyalkanoate from at least one of an ω-substituted alkanoic acid (3) having at least one of phenyl structure and thienyl structure and an ω-cyclohexylalkanoic acid (4) having a cyclohexyl structure in a culture medium containing at least one of the compound (3) and the compound (4) and a hydroxyl group-having compound.
