Enzymatic Method for Sustainable Polyhydroxyalkanoates from Biomass
The invention relates to an enzymatic-chemical method for
obtaining polyhydroxyalkanoates (PHA) or the copolymers thereof, from biomass. The inventive method comprises chemically the biomass with rdeducing agent that reduces the non-PHA cell components of the biomass. The chemical treatment is carried out before and/or after the enzymatic cell disruption. The inventive method allows, unlike other cell disruption techniques, for obtaining polyhydroxyalkanoates from biomass with a low PHA content (for example <60%) in a simple and reliable way, without drastically changing or deteriorating the polymer properties or polymer purity. For the patented method no PHA/PHB solvents (or only small quantities) are needed, thus eliminating health risks for the operator and environmental hazards.
