ABSTRACT:
A method is provided which biosynthesizes a PHA having an epoxy group on a side chain with improved physicochemical properties. Specifically, a method of producing a polyester containing an epoxy group in a side chain thereof using alkene as a raw material is provided which comprises the steps of bringing alkene into contact with a microorganism having an ability to uptake alkene and convert it to a polyester and allowing the microorganism to convert the alkene into a polyester containing an epoxy group in a side chain thereof. Further, a method of producing a crosslinked polymer is provided which comprises reacting the polyester obtained by the above mentioned method with a diamine compound.
