- Abstract
The ability of wild-type strain Cupriavidus eutrophus B10646 to synthesize copolymers containing 3-hydroxy-4-methylvalerate (3H4MV) [P(3HB/3HV/3H4MV)] was studied. The possibility of synthesis of terpolymers containing 3HB, 3HV and 3H4MV monomers using glucose, or butyric acid and co-substrate was shown. A family of copolymers with different content of 3H4MV monomer was synthesized. The highest content of 3H4MV was 7.7 mol. %. Increase of 3HV and 3H4MV content in copolymers caused the reduction of crystallinity degree and of molecular weight, and changes of thermal characteristics of copolymers
