have recently been found to decrease the dry weight production in the same C. reinhardtii strain (Mortensen and Gislerød 2014).
Fischer et al. (2006) showed that cells of the same species were more susceptible to high-light stress under high CO2 concentrations than under low concentrations. In the present study, however, the negative effect of the high concentrations seemed to be more related to a high growth rate than to high-light conditions.
