摘要：
The present invention provides a method for easily obtaining a biodegradable polyhydroxyalkanoate by a solvent extraction method. A method for producing a polyhydroxyalkanoate crystal which comprises mixing a solution of a polyhydroxyalkanoate in a good solvent with a poor solvent at 50 to 130° C. to precipitate a polyhydroxyalkanoate.
