Research Abstract

This study first showed that ammonia oxidation by thermophilic archaea mainly provided chemical energy for the development of microbial community in an ammonia-rich hot spring. In contrast, culture experiments first suggest that nitrogen fixation by hyperthermophilic methanogen is a key process to regulate primary production of subsurface microbial communities in ammonia-poor hydrothermal environments.
