ABSTRACT:
The present invention relates to a process for recovering polyhydroxyalkanoate from biological source material containing the polyhydroxyalkanoate, the process comprising: a) comminuting the biological source material; b) suspending the comminuted biological source material in a fluid; c) partitioning the polyhydroxyalkanoate from the other components of the biological source material by centrifugal fractionation to from a solid-solid separation; and d) recovering the polyhydroxyalkanoate.
