| 摘要 |
Polyhydroxyalkanoate (PHA) polyester is recovered from vegetable matter associated with its production in transgenic plants. The process involves contacting the vegetable matter with one or more reagents inactive toward PHA but effective to solubilize at least part of the vegetable matter, taking off the resulting solution, and recovering PHA from the residue enriched therein. Effective solubilizing reagents that are preferred include enzyme formulations comprising carbohydrases, hydrolases or proteases.
