NOVELTY - Extracting suspended lipids from an aqueous suspension, comprises: providing a suspension (310) including an aqueous liquid and suspended particles, where the suspended particles include lipids substantially contained within polar exterior layers; adding a nonpolar solvent (320) to the suspension to form a mixture; disrupting the exterior layers (330) to expose the lipids to the nonpolar solvent; and segregating the mixture (340) into first and second products, where the first product has a higher amount of the lipids than the second product.    USE - The method is useful for extracting suspended lipids, which is useful for producing biofuel (all claimed).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a material comprising at least one of the non-lipid biomass substances fabricated;    (2) a lipid extracted from an aqueous suspension using the method;    (3) a biofuel synthesized from a substance extracted from an aqueous suspension using the method;    (4) a method comprising: providing a suspension in a pressure vessel, where the suspension includes suspended cells in natural or synthetic seawater, and the cells include lipids substantially contained within polar exterior layers; adding hexane to the suspension to form a mixture; heating the mixture at 20-200 degrees C; controlling a pressure above the heated mixture to a value that prevents boiling of the hexane or seawater; agitating the heated mixture to disrupt the exterior layers; and segregating the agitated mixture into first and second products, where the first product has a majority of the lipids, and the second product has a majority of the seawater;    (5) a particulate material fabricated according to the method, comprising: providing a suspension including an aqueous liquid and suspended cells, the suspended cells having a mean size below 100 microns and including lipids substantially contained within walls of the cells; adding a nonpolar solvent to the suspension to form a mixture; disrupting the cell walls to expose the lipids to the nonpolar solvent; segregating the mixture into first, second, and third products, where the first product contains a majority of the cell walls, the second product contains a majority of the lipids, and the third product contains a majority of the aqueous liquid; and removing the first product; and    (6) a system for extracting substances from a suspension, comprising: a disruption station having a first inlet to receive the suspension, the suspension including: a liquid, and suspended particles having exterior layers that are chemically compatible with the liquid and interiors having at least a portion that is substantially immiscible with the liquid, the disruption station having a second inlet to receive a solvent that dissolves the portions of the interiors that are immiscible with the liquid, the disruption station configured to disrupt the exterior layers; and a segregation station configured to segregate the disrupted suspension into at least first and second segregation products, the first segregation product including a greater amount of the solvent and dissolved portions than the second segregation product.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of extraction of suspended lipids.    Providing suspension (310)    Adding solvent (320)    Disrupt exterior; (330)    Segregating the mixture (340)    Adjust chemistry. (322)
