Corals are animals that form close mutualistic associations with endosymbiotic photosynthetic algae of the genus Symbiodinium. Together they provide the calcium carbonate framework of coral reef ecosystems. The importance of the microbiome (i.e., bacteria, archaea, fungi, and viruses) to holobiont functioning has only recently been recognized. Given that growth and density of Symbiodinium within the coral host is highly dependent on nitrogen availability, nitrogen-cycling microbes may be of fundamental importance to the stability of the coral-algae symbiosis and holobiont functioning, in particular under nutrient-enriched and -depleted scenarios. We summarize what is known about nitrogen cycling in corals and conclude that disturbance of microbial nitrogen cycling may be tightly linked to coral bleaching and disease.
珊瑚与共生的光合藻类属共生。它们共同为珊瑚礁生态系统提供碳酸钙框架。微生物组（即细菌、古菌、真菌和病毒）对整个生物的功能的重要性最近才被认识到。鉴于共生藻在珊瑚宿主中的生长和密度高度依赖于氮的供应，氮循环微生物可能对珊瑚-藻类共生体和整个生物的稳定性，特别是在富营养化和贫营养化的情况下，具有重要意义。我们总结了珊瑚中氮循环的已知情况，并得出结论，微生物氮循环的干扰可能与珊瑚白化和疾病密切相关。
