摘要： A method of isolating nutraceuticals products from algae is provided. A method of isolating carotenoids and omega-3 rich oil from algae includes dewatering substantially intact algal cells to make an algal biomass and adding a first ethanol fraction to the algal biomass. The method also includes separating a first substantially solid biomass fraction from a first substantially liquid fraction comprising proteins and combining the first substantially solid biomass fraction with a second ethanol fraction. The method further includes separating a second substantially solid biomass fraction from a second substantially liquid fraction comprising polar lipids and combining the second substantially solid biomass fraction with a third ethanol solvent fraction. The method also includes separating a third substantially solid biomass fraction from a third substantially liquid fraction comprising neutral lipids, wherein the third substantially solid biomass fraction comprises carbohydrates and separating the neutral lipids into carotenoids and omega-3 rich oil.

摘要： A method for separating neutral lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting neutral lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal neutral lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. The neutral lipids are removed after first removing a polar lipid fraction and a protein fraction. These neutral lipids can be used to generate renewable fuels as well as food products and supplements.

摘要： Methods for selective extraction and fractionation of algal proteins from an algal biomass or algal culture are disclosed. A method of selective removal of products from an algal biomass provides for single and multistep extraction processes which allow for efficient separation of algal proteins. These proteins can be used as renewable sources of proteins for animal feedstocks and human food. Further, lipids remaining in the algal biomass after extraction of proteins can be used to generate renewable fuels.

摘要： A method for separating polar lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting polar lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal polar lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. These polar lipids are high value products which can be used as surfactants, detergents, and food additives. Neutral lipids remaining in the algal biomass after extraction of polar lipids can be used to generate renewable fuels.

摘要： A method for producing biofuels is provided. A method of making biofuels includes dewatering substantially intact algal cells to make an algal biomass, sequentially adding solvent sets to the algal biomass, and sequentially separating solid biomass fractions from liquid fractions to arrive at a liquid fraction comprising neutral lipids. The method also includes esterifying the neutral lipids, separating a water miscible fraction comprising glycerin from a water immiscible fraction comprising fuel esters, carotenoids, and omega-3 fatty acids. The method also includes obtaining a C 16 or shorter fuel esters fraction, a C 16 or longer fuel ester fraction, and a residue comprising carotenoids and omega-3 fatty acids. The method includes hydrogenating and deoxygenating at least one of (i) the C16 or shorter fuel esters to obtain a jet fuel blend stock and (ii) the C16 or longer fuel esters to obtain a diesel blend stock.
