Mangrove wetlands possess four important characteristics as one of the unique marine
ecosystems, and are found in the intertidal coastal regions of the tropics and subtropics in …

Nitrogen (N) is a key element for life in the oceans. It controls primary productivity in many
parts of the global ocean, consequently playing a crucial role in the uptake of atmospheric …

Diversity, abundance, and activity of ammonia-oxidizing bacteria (AOB) and ammonia-
oxidizing archaea (AOA) were investigated using the ammonia monooxygenase α subunit …

The anaerobic oxidation of ammonium (anammox) process has been observed in diverse
terrestrial ecosystems, while the contribution of anammox to N2 production in paddy soils is …

Although low-oxygen nitrification can significantly cut down the aeration demand in
wastewater treatment plants, little is known about the community dynamics of relevant …

Ammonia oxidation plays a significant role in the nitrogen cycle in marine sediments.
Ammonia-oxidizing archaea (AOA) and bacteria (AOB) are the key contributors to ammonia …

Background Subseafloor sediments accumulate large amounts of organic and inorganic
materials that contain a highly diverse microbial ecosystem. The aim of this study was to …

Archaea have multiple roles in global biogeochemical cycles. However, we still have limited
knowledge about how environmental factors affect the diversity and function of different …

Archaea are diverse and ubiquitous prokaryotes present in both extreme and moderate
environments. Estuaries, serving as links between the land and ocean, harbor numerous …

Anaerobic ammonium-oxidizing (anammox) bacteria, aerobic ammonia-oxidizing archaea
