The production cost of polyhydroxyalkanoates is high and the production process needs to be improved as soon as possible.

polyhydroxyalkanoate (pha) is an intracellular polyester synthesized by bacteria and is a substance that stores carbon sources and energy in organisms. polyhydroxyalkanoate not only has physical and chemical properties similar to those of synthetic plastics, but also has excellent properties such as biodegradability, biocompatibility, optical activity, piezoelectricity, and gas barrier properties. it is an ideal…
