Effects of different incident photon fluxes on the accumulation of fucoxanthin and chlorophyll a in P. tricornutum under red LED illumination. a Fucoxanthin and chlorophyll a content in PT-7 and PT-8 medium under different incident photon fluxes; b ratio of fucoxanthin to chlorophyll a under different incident photon fluxes. The results are average values from either two or three independent experiments. Error bars indicate SE. Asterisk (*) represents statistically significant difference of the ratio between the two groups. The symbols aa and ab represents statistically significant difference of pigment content between the two groups. The symbols bc and bd represents statistically significant difference of pigment content between the two groups. The symbols cd and ce represents statistically significant difference of pigment content between the two groups
