| titleOfInvention | Method of producing polyhydroxyalkanoate |
| abstract | The present invention has its object to provide a method of producing PHA by extracting, separating, and purifying PHA from biomass containing PHA having an weight average molecular weight of more than 2,000,000, by which smooth stirring can be carried out during extraction and filterability of a residue becomes good to thereby efficiently produce PHA with good operability. In the present invention, PHA is extracted, separated, and purified from biomass by a method of producing polyhydroxyalkanoate by extracting and isolating polyhydroxyalkanoate by using an aprotic organic solvent from biomass containing polyhydroxyalkanoate having a weight average molecular weight of more than 2,000,000, which comprises decreasing the weight average molecular weight of the polyhydroxyalkanoate through any one of the following treatments: (a) the biomass is heated at 40 to 500 DEG C. before addition of the aprotic organic solvent; (b) the biomass is heated at 40 to 500 DEG C. before addition of the aprotic organic solvent, and is further heated at 40 to 200 DEG C. in the aprotic organic solvent; (c) the biomass is heated at 40 to 500 DEG C. before addition of the aprotic organic solvent, and is further heated at 40 to 200 DEG C. in the aprotic organic solvent in the presence of water and/or an alcohol; (d) the biomass is not heated before addition of the aprotic organic solvent, but is heated at 40 to 200 DEG C. in the aprotic organic solvent; and (e) the biomass is not heated before addition of the aprotic organic solvent, but is heated at 40 to 200 DEG C. in the aprotic organic solvent in the presence of water and/or an alcohol. |
