Table 4.

The physiological parameters (±SE) of the C-specific C-fixation versus CO₂ concentration response curves for T. erythraeum IMS101, fitted using the Michaelis–Menten model to obtain estimates using the combined data from all replicates from both experiments employing varied TIC at fixed pH and varied pH at fixed TIC for each CO₂ treatment

Parameter	Units	Low CO₂	Mid CO₂	High CO₂
V _C,max	h^–1	0.011 (0.0002)	0.024 (0.0007)	0.026 (0.0008)
K _m	µM CO₂	0.8 (0.1)	2.2 (0.3)	3.2 (0.4)
Affinity	mM (CO₂)^–1 h^–1	13.3 (1.7)	10.9 (1.5)	8.0 (1.0)

V _C,max, the C-specific maximum C-fixation rate; K_m, the half saturation constant; Affinity, the C-specific initial slope of the V_C,max versus CO₂-response curve.
