Changes of total Se incorporation to biomass during a 3-day experiment in Chlorella cultures exposed to various Se doses (2.5, 8.5 and 25 mg Se per g of DW) under 250 µmol photons m−2 s−1 (a) and various light intensities (250, 500 and 750 µmol photons m−2 s−1) in the presence of 16 mg Se g−1 DW (b). *P < 0.05 means significant difference compared to the control (no Se added)
