在曝气（350ppm CO2）培养基中，珊瑚（Corallina pilulifera Postels et Ruprecht）的钙化表现出日变化，光照时期的钙化速度比黑暗时期快。添加CO2（空气+ 1250 ppm）抑制钙化。这是由于二氧化碳的加入降低了pH值。在pH恒定为8.2时，海水中溶解无机碳浓度升高，光合作用和钙化作用均增强。
Calcification in Corallina pilulifera Postels et Ruprecht displayed diurnal variations in aerated (350 ppm CO2) culture media, with faster rates during the light than during the dark period. Addition of CO2 (air + 1250 ppm) inhibited calcification. This was attributable to the decreased pH resulting from CO2 addition. Both photosynthesis and calcification were enhanced in seawater, with elevated dissolved inorganic carbon concentrations at a constant pH of 8.2.
