| 摘要 |
The present invention provides methods for the production of poly- beta -hydroxybutyrate, comprising the steps of (a) introducing into a prokaryotic host cell capable of metabolizing sucrose a vector construct which directs the expression of a sequence which encodes a poly- beta -hydroxybutyrate biosynthetic pathway, (b) culturing the host cell in medium containing sucrose, and (c) isolating poly- beta -hydroxybutyrate from the cultured host cell.
