Changes of the nitrate concentration, intracellular nitrogen and carbon content in the wild-type and transgenic strains during aerated cultivation. a Nitrate concentrations in the normal cultivated algal cultures. b Nitrate concentrations in the high-CO2 cultivated algal cultures. c Differences in intracellular C/N ratio between high-CO2 cultivated wild-type and G6PDH engineered strains. Data were shown as mean values ± SD for three independent experiments. WT the wild-type P. tricornutum strain
