The Chl a (a), fucoxanthin (b), Dtx (c) and Ddx (d) contents per cell as a function of medium light (ML) or high light (HL) exposure time. Cultures were grown exponentially at a light intensity of 30 μmol photons m−2s−1 for 4 weeks prior to HL treatment. Error bars represent the standard deviations of the means from three biological replicates. Different letters indicate significant differences between light regimes at P < 0.05
