ABSTRACT B.32943 "Separation Process" An aqueous suspension of micro-organsim cells containing a 3-hydroxybutyrate polymer are subjected to a proteolytic enzyme digestion or a surfactant digestion in order to solubilize 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°C to denature nucleic acids which otherwise hinder separation of the 3-hydroxybutyrate polymer containing residue from the suspension.
