Comments "Many measurements of cyanobacterial and microalgal photon yields using gas exchange (not just fluorescence) have been carried out on organisms grown on high CO2. However, some measurements were made on cultures of marine microalgae, bubbled with air, that are expressing CCMs [carbon dioxide concentrating mechanisms], and experimented on without CO2 enrichment (Welschmeyer and Lorenzen 1981 Geider et al. 1985, 1986) (Table 3). There are also data on marine macroalgae grown and experimented on with air-equilibrium carbon dioxide concentrations (Lu¨ning and Dring 1995 Markager 1993). Lu¨ning and Dring (1995) used marine macroalgae expressing, or not possessing, CCMs, while Markager (1993) worked on marine macroalgae which all expressed CCMs (Table 3)."
