Effect of nutrient depletion on biomass and lipid production in the centric diatoms T. weissoflogii (white) and C. cryptica (gray). t0 = starting point of limitation experiments; Rp = replete conditions; −N = nitrogen limitation (20% of standard concentration in f/2 medium); −Si = silicon limitation (20% of standard concentration in f/2 medium).
