Process for producing biodegradable polyester

摘要

There is provided a method for producing a biodegradable polyester capable of controlling various physical properties of the biodegradable polyester. A poly(3-hydroxyalkanoate) biosynthetic enzyme is altered by an evolutionary-engineering technique, and the poly(3-hydroxyalkanoate) biosynthetic enzyme is expressed in a host to synthesize various copolymers in the host.
