Process for the isolation of polyhydroxyalkanoates (PHAs) from bacterial cells by solvent extraction
A process for extracting and recovering polyhydroxyalkanoates (PHAs) from cellular biomass comprising the steps of: extracting the polyhydroxyalkanoate with at least one non-halogenated solvent which is non-aggressive to the environment; heating the cellular biomass, in order to form a suspension co...

| description | A process for extracting and recovering polyhydroxyalkanoates (PHAs) from cellular biomass comprising the steps of: extracting the polyhydroxyalkanoate with at least one non-halogenated solvent which is non-aggressive to the environment; heating the cellular biomass, in order to form a suspension comprising PHA solvent with the dissolved PHA and insoluble residues; recovering the solvent enriched with PHA; injecting the PHA-enriched solvent in a vapor flow in order to rapidly promote the complete precipitation of PHA in water, while processing the solvent evaporation; depleting the residual solvent; separating the purified PHA particles from the suspension and drying them. |
