(A) Chl a cell−1 and echinenone/Chl a, (B) (Dd + Dt)/Chl a, Dt/Chl a, de-expoxidation ratio (DES) in Tisochrysis lutea grown under various light and nutrient conditions (see Table 1). Each data point is the mean of 2 to 3 independent cultures, error bars represent standard deviations. *Note that in A, Chl a cell−1 is not available under P starvation.
