AB The large-scale biomass production is an essential step in the biotechnological applicationsof microalgae. Coccomyxa onubensis is an acidophilic microalga isolated from the highly acidic watersof Río Tinto (province of Huelva, Spain) and has been shown to accumulate a high concentrationof lutein (9.7 mg g-1dw), a valuable antioxidant, when grown at laboratory-scale. A productivityof 0.14 g L-1 d-1 was obtained by growing the microalga under outdoor conditions in an 800 Ltubular photobioreactor. The results show a stable biomass production for at least one month andwith a lutein content of 10 mg g-1dw, at pH values in the range 2.5–3.0 and temperature in the range10–25 ºC. Culture density, temperature, and CO2 availability in highly acidic medium are rate-limitingconditions for the microalgal growth. These aspects are discussed in this paper in order to improvethe outdoor culture conditions for competitive applications of C. onubensis.
