Abstract: A PHA copolymer which is slowly crystallized is improved in crystallization speed to improve the melt workability of the PHA copolymer in working such as injection molding, film molding, blow molding, fiber spinning, extrusion foaming or bead foaming, thereby improving the resultant articles in productivity. A method for the improvement is a method for producing a PHA mixture, including the step of culturing a microorganism having both of a gene encoding a PHA synthase that synthesizes a copolymer PHA (A) and that is derived from the genus Aeromonas, and a gene encoding a PHA synthase that synthesizes a PHA (B) different in melting point from the copolymer PHA (A) by 10° C. or more to produce, in a cell of the microorganism, two or more PHAs different in melting point from one another by 10° C. or more simultaneously.

Abstract: The purpose of the present invention is to improve processability in the melt-molding by improving the slowness of crystallization that is a disadvantage of polyhydroxyalkanoate, which is slow to crystallize, and to improve processing speed. Provided is a polyester resin composition including a first polyhydroxyalkanoate and a second polyhydroxyalkanoate, wherein the melting point of the second polyhydroxyalkanoate in the polyester resin composition is observed at a temperature lower than the melting point measured for the second polyhydroxyalkanoate alone.
