The invention provides a recombinant bacteria and a method for producing P(3HB-4HB-3HV) by fermentation using the recombinant bacteria, and also provides a method for adjusting the monomer ratio in P(3HB-4HB-3HV). The present invention reconstructs and constructs a recombinant bacteria that can produce P (3HB-4HB-3HV) by transforming microorganisms that cannot produce P (3HB-4HB-3HV) originally, and at the same time, culturing the recombinant bacteria can well increase the amount of The content of 4HB and 3HV in P(3HB-4HB-3HV) can obtain P(3HB-4HB-3HV) material with excellent performance. |
