(57) [Summary] [Structure] A bacterium having an ability to produce poly-3-hydroxybutyrate is mainly grown in the preceding stage, By contacting with a mixture of a carbon source that can be utilized by the bacterium in the latter stage and a primary alcohol of 3 to 7, a mixture of D-3-hydroxybutyrate and D-3-hydroxyvalerate is introduced into the cells. The polymer is accumulated synthetically. [Effect] D-3-hydroxybutyrate and D-3- A copolymer composed of hydroxyvalerate can be produced in large quantities and at low cost. |
