Growth of C. gracilis (a) and P. tricornutum (b) with or without vitamins. Cells precultured in same culture medium at least twice, then inoculated into fresh medium at logarithmic or stationary phase (red or black lines, respectively) at an OD730 of ~0.07; cells cultivated at room temperature with photon irradiance of 50 µmol photons m−2 s−1 in F/2-enriched seawater with (closed symbols and solid lines) or without (open symbols and dashed lines) vitamins; and ambient air bubbled through media
