Fig. 2. Cell population growth of Desmodesmus subspicatus between 24 and 50 h of the 72 h growth experiment at a time resolution of 2 h. Figure 2a displays the values for in vivo chlorophyll autofluorescence and the fit of the growth model provided in Eq. 1. The inset shows the values within the 72 h full experiment. Figure 2b depicts the values for cell counts for the same experiment.
