长期以来，人们都知道虫黄藻珊瑚在光照下比在黑暗中钙化得更快，但这一过程的机制一直不确定。在这里，我们测试的影响下，控制二氧化碳分压条件和固定的碳源zooxanthellate和漂白的小菌落的分支珊瑚Stylophora pistillata钙化的氧气。在虫黄藻小菌落，氧气增加了黑暗的钙化率的水平相媲美的光测。然而，在漂白的小菌落中，单独的氧气并不能增强钙化，但当与固定碳源（葡萄糖或甘油）结合时，钙化增加。呼吸速率增加响应氧气与更大的增加时，氧气与固定碳结合。ATP含量在很大程度上不受治疗的影响，除了甘油降低ATP水平。
Zooxanthellate corals have long been known to calcify faster in the light than in the dark, however the mechanism underlying this process has been uncertain. Here we tested the effects of oxygen under controlled pCO2 conditions and fixed carbon sources on calcification in zooxanthellate and bleached microcolonies of the branching coral Stylophora pistillata. In zooxanthellate microcolonies, oxygen increased dark calcification rates to levels comparable to those measured in the light. However in bleached microcolonies oxygen alone did not enhance calcification, but when combined with a fixed carbon source (glucose or glycerol), calcification increased. Respiration rates increased in response to oxygen with greater increases when oxygen is combined with fixed carbon. ATP content was largely unaffected by treatments, with the exception of glycerol which decreased ATP levels.
