Algae due to their potential of high productivity have attracted
considerable attention as a biomass for biofuel production [1–3].
Algae also have many other attractive attributes, one of which is
their suitability for producing “drop-in” fuel, as their high content of
lipid can be used as feedstock as petroleum replacement upon
hydro-treatment [1,2]. However, there are various techno-economic
technical barriers that need to be overcome in order to produce
algae fuel on an industrial scale. Identifying and obtaining valueadded
co-products from the algal biomass in addition to lipid are
among the most appropriate approaches to address the challenge
of economics [4]. Critical prerequisite for commercializing the
co-products includes (1) coupling co-product extraction with algal
lipid extraction, and (2) developing products targeting a wide range
of industries to avoid market saturation.
