Table 1.

Corrected δ¹³C isotopic discrimination (δ¹³C_microalgae) and pH compensation point for E. huxleyi under the different experimental conditions on day 9; HC-LP (pCO₂: 1000–1200 µatm; pH: 7.6–7.8), LC-HP (pCO₂: 380–390 µatm; pH: 8.2), and LC-LP (pCO₂: 380–390 µatm; pH: 7.6–7.8). Values are mean ± SD. Significant differences between treatments are indicated by different letters (p < 0.05)
