The present invention provides a microorganism that synthesizes a high-molecular-weight PHA, and a method for producing a high-molecular-weight PHA, which have a productivity of at least 100 g/L. The provision is achieved by controlling the specific activity of a PHA synthase in cells of a microorganism that belongs to the genus Cupriavidus and is capable of producing a PHA, to 0.1 U/mg-protein at most. The microorganism and the method enable industrially efficient production of a PHA with a weight average molecular weight of at least 4,000,000. |
