청구항

The invention claimed is: 1. A method for producing a polyhydroxyalkanoate crystal which comprises extracting a polyhydroxyalkanoate using a monohydric alcohol having 4 to 10 carbon atoms as an extraction solvent, keeping a polyhydroxyalkanoate solution containing 0.1 to 10% by weight of water relative to the total amount of the solution warm at 70째 C. or higher, and cooling the solution to below 70째 C. to precipitate a polyhydroxyalkanoate crystal. 2. The method for producing a polyhydroxyalkanoate crystal according to claim 1, wherein the monohydric...
