PROCESS FOR RECOVERY OF POLYHYDROXYALKANOATES FROM BIOMASS

摘要

Systems and processes for the recovery of polyhydroxyalkanoates ('PHA') from biomass are disclosed. In certain embodiments, the process includes the steps of extracting at least a portion of PHA from a disrupted quantity of PHA-containing biomass with an acetin solvent to produce a biomass phase (including residual biomass) and a PHA phase including at least a portion of the PHA from the biomass. The biomass phase and the PHA phase are separated, and at least a portion of PHA may be isolated from the PHA phase. Systems and processes including multiple disruption and/or extraction steps also are disclosed.
