Cultures of D. salina on glycerol and controls. (a) IM, 1.5 M NaCl and 50 µmol m⁻² s⁻¹. (b) Gly, 3.0 M NaCl and 50 µmol photons m⁻² s⁻¹. (c) IM, 1.5 M NaCl and 300 µmol photons m⁻² s⁻¹. (d) Gly, 3.0 M NaCl and 300 µmol photons m⁻² s⁻¹. The images were captured on the seventh day of culture when the pigments were analyzed. (a) and (b) correspond to the original culture flasks, whereas (c) and (d) are recipients only used for photography.
