Fig. 5 — Carbon fixation rate showing K_M (µM) and V_max (nmol C · 10⁶ cell⁻¹ · h⁻¹) for E. huxleyi in d₄ under HC-LP (1000–1200 µatm and pH 7.6–7.8), LC-HP (380–390 µatm and pH 8.1), and LC-LP (380–390 µatm and pH 7.6–7.8) treatments. DIC concentrations in the assay medium were 50, 150, 500, 1000, 2000, and 4000 µM. The kinetic parameters were calculated by fitting to Michaelis–Menten kinetics. Values are mean ± SD (n = 3). Significant differences between treatments are indicated by different letters (p < 0.05)
