Comammox bacterial abundance, activity, and contribution in agricultural rhizosphere soils
Science of The Total Environment, 2020The newly identified complete ammonia oxidation (comammox), which is capable of oxidizing ammonia directly to nitrate, has complemented our knowledge of nitrification in the global nitrogen (N) cycle. However, understanding the contribution and ecological roles of comammox in complex soil environments is still in its infancy.

Comammox biogeography subject to anthropogenic interferences along a high-altitude river
Water Research, 2022The recent discovery of comammox Nitrospira performing complete ammonia oxidation to nitrate has overturned the long-held dogma of two-step nitrification on Earth, yet little is known about the effect of urbanization interference on their distribution.

Specific Micropollutant Biotransformation Pattern by the Comammox Bacterium Nitrospira inopinata
Environmental Science & Technology, 2019The recently discovered complete ammonia-oxidizing (comammox) bacteria occur in various environments, including wastewater treatment plants. To better understand their role in micropollutant biotransformation in comparison with ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), we investigated the biotransformation capability of ...

[Research progress on primers and molecular ecology of comammox Nitrospira].
Ying yong sheng tai xue bao = The journal of applied ecology, 2021Nitrification is a key process in nitrogen cycling, which has received considerable attention in the research field of soil biochemistry. In 2015, the discovery of complete ammonia oxidizers (Comammox) challenged conventional two-step nitrification perspective, which represented a paradigm shift in the understanding of soil nitrogen cycling.

The environmental detection of comammox Nitrospira
2017Vor kurzem wurden die ersten Mikroorganismen entdeckt, die in der Lage sind Ammonium komplett zu Nitrat zu oxidieren (‘comammox’), und dadurch das Dogma, über die Arbeitsteilung in der Nitrifikation in zwei aufeinanderfolgenden Schritten, für ungültig erklärt.

Comammox and AOA responses to ammonia loading rate in oligotrophic environments
Water ResearchNitrification is a central process in the global nitrogen cycle, yet the ecological niches and growth strategies of ammonia-oxidizing microorganisms in oligotrophic environments remain poorly understood. To investigate the ecological responses of complete ammonia oxidizers (Comammox) and ammonia-oxidizing archaea (AOA), a membrane bioreactor (MBR ...

Comammox Nitrospira are the dominant ammonia oxidizers in the Yangtze estuarine biofilms
Water ResearchBiofilms are indispensable ecological habitats for microbes that have garnered global attention and play a potential role in influencing the biogeochemical cycling of nitrogen. However, the biogeochemical significance of biofilms and the mechanisms by which they regulate nitrogen cycling remain elusive.

Comammox ammonia oxidization and N2O production in vadose and saturated zone soils
Water ResearchRiparian zones are biogeochemical hotspots of N2O emission. The important role of ammonia oxidation in N2O production has been reported in rivers, even higher than heterotrophic denitrification, however, the mechanisms controlling riparian N2O production remain unknown.
