Abstract
The object of the present invention is to provide a method for producing a PHA having a low water content. The object is attained by providing a method for producing a PHA, including a filtration step of filtering an aqueous PHA suspension having a pH of 2.5 to 5.5, by filter-pressing with use of a filter medium having an air permeability of 0.1 cm3/cm2/min to 2.5 cm3/cm2/min, the aqueous PHA suspension having a liquid density of 0.50 g/mL to 1.08 g/mL in the filtration step, the filtration step including a compression step and an air blow step.
