Abstract
A method comprising a series of selective extraction techniques for the parallel production of biodiesel and isolation of several valuable co-products including an alkenone hydrocarbon mixture of the kerosene/jet fuel range (primarily C10-, C12-, and C17-hydrocarbons) and fucoxanthin, a high-valued carotenoid, from the marine alkenone-producing microalgae Isochrysis.
Claims17
A method of isolating at least one product from algae, the method comprising:
- (a) growing an algal mariculture capable of producing alkenones;
- (b) extracting the algal mariculture with a non-polar liquid solvent to produce an extraction mixture;
- (c) separating the extraction mixture into at least a first fraction and a second fraction, wherein the first fraction is a lipid-containing mixture including alkenones and less than 50% (w/v) fatty acid methyl esters (FAMEs);
- and
- (d) isolating a mixture of alkenones, lipids, and FAMEs from the first fraction.
