EXTRACTION OF POLYHYDROXYALKANOATES WITH SOLVENT FROM BIOMASS ALLEVIATED BY USING MARGINAL NON-SOLVENT FOR POLYHYDROXYALKANOATES Russian patent published in 2003 - IPC

Abstract RU 2196177 C2

FIELD: biotechnology. SUBSTANCE: method of isolation of polyhydroxyalkanoate from biomass involves the following stages: (a) treatment of biomass with solvent of polyhydroxyalkanoate and marginal non-solvent for polyhydroxyalkanoate; (b) removal of any insoluble biomass resulting to formation of suspension of precipitated polyhydroxyalkanoate in marginal non-solvent for polyhydroxyalkanoate. Method involves optional removal of marginal non-solvent for polyhydroxyalkanoate resulting to remaining polyhydroxyalkanoate. Invention relates also to polyhydoxyalkanoate suspension prepared by this method. Method ensures to obtain polyhydroxyalkanoate easily and economically. EFFECT: improved method of extraction and preparing. 9 cl, 1 dwg, 4 ex
