摘要: The invention discloses a method for production of polyhydroxybutyrate-co-polyhydroxyvalerate (PHBV) by recombinant Escherichia coli harboring plasmid containing both phaCAB and prpE. Different percentage of hydroxyvalerate can be obtained from the recombinant E. coli when cultivated in the medium containing different concentrations of propionic acid. In this patent, we provide a method that integrated all of the genes (i.e. phaCAB, vgb and prpE) required for PHBV production into a single plasmid. The plasmids were then transformed into an E. coli host. Results showed that PHBV can be produced by this recombinant E. coli, and the ration of HV to HB in the co-polymers can be regulated by addition of different concentrations of propionic acid in the medium. The percentage of HV in the co-polymers can be adjusted from about 3% up to more than 35%.
