  • Publication number: 20060057692
    Abstract: The invention relates to processes for extracting polyhydroxyalkanoate from a biomass, comprising admixing the biomass with an organic solvent for from 1 second to 15 minutes at a first temperature of from 5° C. below the melting point of the polyhydroxyalkanoate to 10° C. above the melting point of the polyhydroxyalkanoate and at a pressure of from 1 bar to 10 bar to provide a composition comprising the organic solvent and polyhydroxyalkanoate.

  • Publication number: 20060057691
    Abstract: The present invention relates to a process for extracting polyhydroxyalkanoate from a biomass, comprising contacting the biomass with an organic solvent for a time, at a first temperature, and under a pressure that are sufficient to extract polyhydroxyalkanoate from the biomass to provide a composition comprising the organic solvent and polyhydroxyalkanoate; cooling the composition at a second temperature, which is at least about 10° C. lower than the first temperature; and mixing the composition at a second temperature with a power to volume ratio of from about 0.001 KW/m3 to about 100 KW/m3.

  • Publication number: 20050287654
    Abstract: Improved processes for extracting polyhydroxyalkanoate from a biomass containing the polyhydroxyalkanoate including the steps of: combining the biomass containing the polyhydroxyalkanoate with a solvent selected from lower chain ketones, and mixtures thereof to form a biomass liquor wherein the biomass liquor comprises less than about 25% water; mixing the biomass liquor for from about 10 to about 300 minutes at a temperature in the range of from about 70° C. to about 120° C.; separating the polyhydroxyalkanoate from the biomass liquor to form a PHA-enriched liquor, wherein the separating occurs at a temperature of at least about 40° C.; mixing the PHA-enriched liquor with water to form precipitated polyhydroxyalkanoate and an impure solvent liquor, wherein the water is mixed with the PHA enriched liquor in the ratio of from at least about 0.4-1 parts of water to one part solvent; and recovering the precipitated polyhydroxyalkanoate from the impure solvent liquor.

  • Publication number: 20050003996
    Abstract: A fabric conditioning article for use in a clothes dryer. The fabric conditioning article having a flexible sheet and a fabric conditioning composition deposited on the sheet. The fabric conditioning composition includes a fabric conditioning agent, perfumed particles and minor components. The perfume particles are a perfume composition incorporated into a porous mineral carrier such as clay and/or zeolite. Optionally, the perfume composition comprises low levels of unstable perfume components. Alternatively, the perfumed particles have a coating material encapsulating at least a portion of the particles. Optionally, the articles are packaged in a container having a moisture barrier to prevent premature release of the perfume therefrom.
