Title:
METHOD FOR PRODUCING POLYHYDROXYALKANOATE AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2023/120193
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for producing PHA which enables efficient filtering. The above problem is solved by providing a method for producing PHA, said method comprising a step for using a filtering material having an airflow rate of 0.01-5.0 cc/cm2/sec to perform dead-end filtration of an aqueous PHA suspension having a pH of 2.5-5.5, wherein the amount of PHA-surface-adhering protein in the aqueous PHA suspension is not more than 2,000 ppm, and the liquid density of the aqueous PHA suspension in the filtration step is 0.50-1.08 g/mL.
