Abstract： |
The present invention discloses a method for separating and extracting polyhydroxy fatty acid ester from bacterial thallus. Said invented technical scheme is characterized by that it uses one kind of several kinds of five-and/or four-carbon alcohol to break the wall of wet-dried cell thallus in which the polyhydroxy fatty acid ester is self formed and extract the polyhydroxy fatty acid ester. In order to raise the extraction efficiency of PHA from wet cell, before extraction the wt cell can be pre-treated by using hydrophilic and oleophilic reagent. |
