TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The algae species are selected from the following: Amphora, Anabaena, Anikstrodesmis, Botryococcus, Chaetoceros, Chlorella, Chlorococcum, Cyclotella, Cylindrotheca, Euglena, Hematococcus, Isochrysis, Monodus, Monoraphidium, Nannochloris, Nannochloropsis, Navicula, Nephrochloris, Nephroselmis, Nitzschia, Nodularia, Nostoc, Oochromonas, Oocystis, Oscillartoria, Parachlorella, Pavlova, Phaeodactylum, Pinguiococcus, Playtomonas, Pleurochrysis, Porphyra, Pseudoanabaena, Pyramimonas, Rhodomonas, Scenedesmus, Selenastrum, Stichococcus, Synechococcus, Tetraselmis, Thalassiosira, and Trichodesmium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The method (M1) further involves: disturbing the lipid-solvent mixture formed according to step (a) under mild conditions in order to facilitate the formation of the lipid-solvent layer. The lipid is saturated, unsaturated, or polyunsaturated. The saturated lipid comprises fatty acids selected from C10, C12, C14-C20, C22, and C24 fatty acids. The concentration of the saturated lipid of the lipid-solvent layer is greater than the concentration of the saturated lipid of the original biomass. The formation of the lipid-solvent layer in step (a) occurs at less than 55 degrees C and at an ambient pressure. The biomass is selected from yeast, cyanobacteria, archea, bacteria, and algae. At least 80% of the lipid-solvent layer is separated from the mixture. The method (M1) further involves using the lipid-solvent component to produce biofuels. The partially delipidated component comprises a selectively delipidated component, and the method further involves using the selectively delipidated component as a food source. The method further involves enriching the selectively delipidated component with at least an unsaturated lipid. The unsaturated lipid used for enriching the selectively delipidated component is selected from the fatty acids consisting of C18, C20, C22, omega-6, omega-3, omega-9, polyunsaturated fatty acids (PUFA), arachidonic acid (ARA), docosahexanoic acid (DHA), eicosapentaenoic acid (EPA), and dihomo-gamma-linolenic acid (DGLA). The method further involves: using the enriched selectively delipidated component as a part of a feed formulation; separating the at least partially delipidated component into fractions comprising a protein fraction, and fractions comprising a carbohydrate fraction; or using the at least partially delipidated component in anaerobic digestion or fermentation. The hydrophobic ionic liquid solvent is non-toxic, and non-volatile. The hydrophobic liquid solvent only interacts with the lipids of interest. The ionic liquid is a protic ionic liquid. The protic ionic liquid is selected from hydronium ionic liquid, ammonium ionic liquid, alkylamomonium ionic liquid, imidazolium ionic liquid, and heterocyclic ionic liquid. The method (M1) further involves: applying an anti-solvent to the lipid-solvent component so that at least 80% of the ionic liquid is removed from the lipid-solvent component, leaving a remaining lipid fraction; recovering the ionic liquid removed from the lipid-solvent component using an excess of water or any compatible polar solvent; and processing the remaining lipid fraction by chemical conversion. The anti-solvent is an inorganic salt solution immiscible with lipid. The method (M2) further involves determining the dry weight of each type of lipid of the remaining lipid fraction. The biomass is lysed before applying step (a). The ionic liquid is applied to the biomass in countercurrent flow. The method (M3) further involves separating the dewatered cells by gravity separation. EXAMPLE - No suitable example is given.
