Table 1 Dry weight and intracellular substances contents in three different CO2 concentrations cultivated P. tricornutum cells. Intracellular substances involved total water-soluble protein, lipids, chlorophyll a + c and RNA concentration. Data are expressed as a mean ± SD (n = 3)
CO2 concentration | Low-CO2 (0.015 %) | Mid-CO2 (0.035 %) | High-CO2 (0.150 %) |
|---|---|---|---|

Lipid content (w/w, % of DCW) | 33.13 ± 1.2 | 35.87 ± 1.7 | 53.71 ± 2.4 |
Chlorophyll a + c concentration (mmol g−1 FW) | 2.52 ± 0.084 | 3.73 ± 0.030 | 3.28 ± 0.084 |
RNA concentration (μg g−1 FW) | 378.10 ± 10.42 | 715.40 ± 15.45 | 562.39 ± 33.51 |
Total water-soluble protein production (mg g−1 FW) | 7.63 ± 0.03 | 12.76 ± 0.04 | 16.29 ± 0.02 |
