Oxidation of ammonia to nitrite by bacteria and archaea is responsible for global emissions
of nitrous oxide directly and indirectly through provision of nitrite and, after further oxidation …

In the Anthropocene, nitrogen pollution is becoming an increasing challenge for both
mankind and the Earth system. Microbial nitrogen cycling begins with aerobic nitrification …

The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a
breakthrough in the history of nitrification research. Nitrospira inopinata, which was obtained …

Excessive ammonia (NH 3) emitted from nitrogen fertilizer application in farmland have
caused serious disturbance to global environment, including reduction of visibility, formation …

The recent discovery of complete ammonia oxidizers (comammox Nitrospira) challenged the
paradigm of the two-step nitrification mediated by two distinct groups of nitrifiers, and raised …

The first and limiting step of nitrification is catalyzed by ammonia-oxidizing archaea (AOA)
and bacteria (AOB). Recently, complete ammonia oxidizers (comammox Nitrospira) have …

Nitrification is the microbial conversion of reduced forms of nitrogen (N) to nitrate (NO3−),
and in fertilized soils it can lead to substantial N losses via NO3− leaching or nitrous oxide …

The recent discovery of complete ammonia oxidation (comammox) process in a single
organism challenged the division of labor between two functional groups in the classical two …

The use of nitrification inhibitors (NIs) with ammonium (NH 4+)-based fertilizers is an efficient
strategy for reducing nitrogen (N) loss by affecting ammonia-oxidizing archaea (AOA) and …

The recent discovery of complete ammonia oxidation (comammox) has increased our
understanding of nitrification. Although comammox has been shown to play an important …
