Process for the extraction of polyhydroxyalkanoates from biomass

摘要

The invention relates to processes for extracting polyhydroxyalkanoate from a biomass, comprising admixing the biomass with an organic solvent for from 1 second to 15 minutes at a first temperature of from 5° C. below the melting point of the polyhydroxyalkanoate to 10° C. above the melting point of the polyhydroxyalkanoate and at a pressure of from 1 bar to 10 bar to provide a composition comprising the organic solvent and polyhydroxyalkanoate.
