| 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.
