上百年来细菌一直被认为是地球氨氧化过程的主要驱动者,2005年海洋中分离到迄今唯一的非极端环境泉古菌,发现其氧化氨态氮获得能源生长,是氨氧化古菌。氨氧化古菌和细菌对地球氨氧化过程的相对贡献率,是目前全球氮循环研究最重要的微生物生态学问题之一。已有的证据表明古菌在海洋氨氧化过程中发挥了重要作用,细菌则是土壤氨氧化过程的主要驱动者。本文重点探讨了原位自然环境下氨氧化古菌的生态学研究进展。
Bacteria have been considered as the main driver of the earth ammoxidation process for more than one hundred years. In 2005, the only non-extremophilic archea isolated from the sea and found that the oxidized ammonia nitrogen was energy-sourced and was an ammonia-oxidizing archaea. The relative contribution of ammonia-oxidizing archaea and bacteria to the ammoxidation of the earth is one of the most important microbial ecological problems in the global nitrogen cycle research. There is evidence that archaea play an important role in marine ammonia oxidation and that bacteria are the main drivers of soil ammonia oxidation. This article focuses on the in situ natural environment ammonia oxidation archaea ecological research progress.
