Cell volume of wild-type and EpFS4 cells under different growth conditions

Light intensity	100 μmol photons m−2 s−1	350 μmol photons m−2 s−1	350 μmol photons m−2 s−1
CO2 conc.	0.04 %	0.04 %	0.30 %
Wild type	1626.9±25.9	2011.0±228.6	2980.9±414.6
EpFS4	1810.7±89.3*	2623.8±191.5*	3357.1±194.5*

Values are given in fl per cell and are the mean ± standard deviation of the analysis of three to seven independent cultures. Asterisks indicate significant differences from the wild-type E. gracilis cells in each growth conditions (*P < 0.05)
