Figure 1

Biomass concentration of P. purpureum (g L−1) during cultivation under three different light intensities (A) 30, (B) 65 and (C) 100 (µmol m−2 s−1); and three different NaNO3 concentrations 0.075 (●), 0.225 (■) and 0.450 (♦) (g L−1). The error is less than 5% or in general, so it is in the range of the symbol size.
