Effects of different incident photon fluxes on the growth and fucoxanthin content in P. tricornutum under combined red and blue (50:50) LED illumination. The results presented are average values from three independent experiments. Error bars indicate SE. Asterisk (*) represents statistically significant difference of growth data or fucoxanthin content at higher light conditions (136 or 204 μmol/m2/s) in comparison with the light condition at 102 μmol/m2/s. NS represents no statistically significant difference
