| Research Abstract |
This study aimed at microbial synthesis of polyhydroxyalkanoate (PHA) copolymers in which two kinds of monomers were highly block-covalently bonded by regulated expression of the biosynthetic genes. Firstly, copolymer biosynthesis pathways suitable for regulatory gene expression were established in Escherichia coli. Then, recombinant strains of E. coli equipped with a regulatory PHA biosynthesis pathways were constructed, and PHA biosynthesis by the strains and structural analyses of accumulated PHAs are nowunder progress.
