Abstract
Archaea are ubiquitous in the ocean and account for 20 percent of all planktonic microbes. Most of them belong to the phylum Thaumarchaeota and are chemolithoautotrophes, oxidizing ammonia as energy and fixing CO2 as carbon source. Ammonia-oxidizing archaea are now recognized to primary control the initial and rate-limiting step of nitrification in the ocean. A high substrate affinity to ammonia and the most energy-efficient aerobic pathway for autotrophy enable them to thrive in nutrientlimited environments, typical of most of the open ocean.
