ABSTRACT:
An aqueous suspension of micro-organism cells containing a 3-hydroxybutyrate polymer are subjected to a proteolytic enzyme digestion and/or a surfactant digestion in order to solubilise cell material other than the 3-hydroxybutyrate polymer.
Prior to, or during the digestion, but before any proteolytic enzyme digestion step, the suspension is heated to at least 80.degree. C. to denature nucleic acids which otherwise hinder separation of the 3-hydroxybutyrate polymer containing residue from the suspension.
