| Research Abstract |
This study is aimed at construction of recombinant methylotrophic bacteria to produce flexible polyhydroxyalkanoate(PHA) copolymers from methanol using Methylobacterium extorquens AM1 as a host strain. The results revealed that M. extorquens wild-type strain accumulates PHA copolymer composed of mostly C4 monomer with a small amount of C_5 unit. The recombinant strains, which can accumulate PHA composed of C_4, C_5, and C_6 unit, was successfully obtained. These strains produced PHA more efficiently than wild-type strain.
