We studied the growth performance and biochemical composition (including
soluble carbohydrates, proteins, lipids, phenols, chlorophyll-a, carotenoid and the C/N-ratio) of Nannochloropsis oceanica under various CO2 concentrations. The cell density of N. oceanic increased with a rise in CO2 concentration and got the high level at a CO2 concentration of 1000ppm or 1500ppm. In addition, except the proteins all tested biochemical composition were significantly affected by CO2 concentration (0.01 <P< 0.05; one factorial ANOVA). However comparing with other biochemical components, the contents of phenols in N. oceanic showed the opposite trends (P<0.01; one factorial ANOVA). In general, the short-term stimulation of elevated CO2 concentration to N. oceanic can promote cell division and synthesis of most of biochemical components (expect proteins and phenols).
