Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for separating and purifying a polyhydroxyalkanoic acid, by which the polyhydroxyalkanoic acid can efficiently and highly purely be separated and purified from microorganisms containing the polyhydroxyalkanoic acid, and which can easily be performed in industrial scales. SOLUTION: This method for separating and purifying the polyhydroxyalkanoic acid is characterized by separating and washing the polyhydroxyalkanoic acid from microorganisms containing the polyhydroxyalkanoic acid, suspending the polyhydroxyalkanoic acid in water not containing an organic solvent, adding a surfactant, and then heating the mixture without subjecting to a crushing treatment.
