    摘要: The present invention provides methods for isolating a PHA. The method comprises combining the PHA, a first solvent and a second solvent to form a combination, the first solvent and the second solvent being capable of forming an azeotrope with the second solvent; and heating the combination to substantially remove the first solvent from the combination. Alternatively, the method comprises combining the PHA, a first solvent, a second solvent and a third solvent to form a combination, the first solvent and the second solvent being capable of forming an azeotrope with the third solvent; and heating the combination to substantially remove the first solvent and the second solvent from the combination.
