TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The algae is Nannochloropsis, Chlorella ( both preferred), diatoms (bacillariophytes), green algae (chlorophytes), blue-green algae (cyanophytes), golden-brown algae (chrysophytes), haptophytes, freshwater algae, saltwater algae, Amphipleura, Amphora, Chaetoceros, Cyclotella, Cymbella, Fragilaria, Hantzschia, Navicula, Nitzschia, Phaeodactylum, Thalassiosira ankistrodesmus, Botryococcus, Chlorococcum, Dunaliella, Monoraphidium, Oocystis, Scenedesmus, Tetraselmis, Oscillatoria, Synechococcus, Boekelovia, Isochrysis, Neochloris oleoabundans, or Pleurochrysis.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method (M1) further comprises: (e) applying temperature, gas pressure, vacuum or combination of gas pressure and vacuum, air drying the column or the container or using a combination of other drying techniques to remove any excess eluent from the column or the container; (f) recycling the eluent for eluting the algae off the column; (g) repeating the steps of saturating to extract the lipid components from a subsequent batch of the aqueous algal suspension or the slurry; and (h) converting the eluted algae in the receiver to fatty Acid methyl esters (FAMEs) or a biodiesel. In the method (M1), the saturation of the column is determined by a presence of the aqueous algal suspension or slurry (Chlorella and/or Nannochloropsis) in a column effluent detected by an optical sensor attached to the base of the column or the container. The method (M2) further comprises: analyzing the eluted solvent comprising the dissolved lipid components by at least one analytical technique comprising HPLC, gas chromatography, fluorescence, thin layer chromatography, or other chromatographic methods; and the steps (b), and (g) as above per se; and converting the concentrated lipid components and oil in the receiver to FAMEs or biodiesel by transesterification, where the transesterification is catalyzed by an acid or a base. Preferred Components: The eluent comprises methanol acidified with sulfuric acid (preferred), methanol with sodium hydroxide, potassium hydroxide, sodium ethoxide or sodium methoxide.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The anion-exchange resins comprise a cross-linked polymer backbone with functional groups comprising quaternary ammonium salts (preferred), tertiary amines, secondary amines, primary amines, organometallic complexes, and/or any charged species manufactured by corona discharge or plasma ion embedment, with a replaceable cation. The polymer backbone is styrene, divinyl benzene, styrene divinyl benzene, polystyrene, formophenolic, acrylic-divinyl benzene, methacryl-divinyl benzene, functionalized styrene monomer, functionalized acrylic monomer, functionalized methacrylic monomer, acrylamide, methacrylamide, epoxy and acrylic monomers, polypropylene, or functionalized polyvinyl chloride polymer. The anion exchange resin is an electrostatically charged polyethylene. The lipid binding resin comprises the polymer backbone, where at least one copolymerizing monomers with various hydrophilic or hydrophobic functional groups are attached to the polymer backbone. In the method (M1), the polymer backbone is crosslinked divinyl benzene or other crosslinked monomers, where the polymer backbone is at least 2% crosslinked. EXAMPLE - No suitable example given.
