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.
