    摘要: Exemplary methods include centrifuging a wet algal biomass to increase a solid content of the wet algal biomass to between approximately 10% and 40% to result in a centrifuged algal biomass, mixing the centrifuged algal biomass with an amphiphilic solvent to result in a mixture, heating the mixture to result in a dehydrated, defatted algal biomass, separating the amphiphilic solvent from the dehydrated, defatted algal biomass to result in amphiphilic solvent, water and lipids, evaporating the amphiphilic solvent from the water and the lipids, and separating the water from the lipids. The amphiphilic solvent may be selected from a group consisting of acetone, methanol, ethanol, isopropanol, butanone, dimethyl ether, and propionaldehyde. Other exemplary methods include filtering a wet algal biomass through a membrane to increase a solid content of the wet algal biomass to between approximately 10% and 40% to result in a filtered algal biomass.

    摘要: A suspension may include an aqueous liquid and suspended particles. The particles may include a nonpolar and/or hydrophobic substance (e.g., a lipid) substantially contained within polar and/or hydrophilic exterior layers. A method for extracting the suspended lipids may include adding a nonpolar solvent to the suspension and disrupting the exterior layers to expose the lipids to the nonpolar solvent. In some cases, particles may also include interior hydrophilic portions (e.g., intracellular water), which may be exposed to the aqueous liquid via disruption of the exteriors. The mixture may be accelerated to segregate the mixture into first and second products. The first product may have a majority of the nonpolar and/or hydrophobic substances. The second product may have a majority of the polar substances.
