A method for producing biofuels is provided that includes dewatering intact algal cells to make an algal biomass, extracting neutral lipids from the algal biomass, and esterifying the neutral lipids with a catalyst in the presence of an alcohol. The method also includes separating a water soluble fraction comprising glycerin from a water insoluble fraction comprising fuel esters and distilling the fuel esters under vacuum to obtain a C16 or shorter fuel esters fraction, a C16 or longer fuel ester fraction, and a residue comprising carotenoids and omega-3 fatty acids. The method further includes hydrodeoxygenating 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. The method further includes supplying the hydrogenation and deoxygenation processes with hydrogen produced from reformed light hydrocarbons or an algae culture.
