Figure 3: Microalgae and Macroalgae. (A) microalgae high rate pond cultivations of Spirulina (Earthrise farms in California USA) [65]; (B) microalgae cultivated in photobioreactors (example depicted is LGem tubular system at Solar Biofuels Research Centre, Australia) can have higher yields for specialty bioproducts[66]; (C) freshly harvested microalgal biomass[66]; (D) macroalgae coastal cultivations of Kappaphycus [67]; (E) macroalgae cultivation of Ulva in open ponds can be scaled to large ponds on land [68]; (F) freshly harvested macroalgal biomass [67].
