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; Km, the half saturation constant; Affinity, the C-specific initial slope of the VC,max versus CO2-response curve.
