Time course profiles of biomass concentration, nitrate concentration, and lipid content during the growth of Chlamydomonas sp. JSC4 on Modified Bold 3 N medium before and after transfer to high-salinity conditions of (a) 3%, (b) 5%, or (c) 7% sea salt. Error bars indicate standard deviation of three replicated experiments. (Light intensity = 200 μmol m-2 s-1; CO2 aeration = 2.0%; CO2 flow rate = 0.05 vvm). DCW, dry cell weight.
