Competitive enrichment of comammox Nitrospira in floccular sludge

Water Research
The discovery of complete ammonium oxidation (comammox) has subverted the traditional perception of two-step nitrification, which plays a key role in achieving biological nitrogen removal from wastewater. Floccular sludge-based treatment technologies are being applied at the majority of wastewater treatment plants in service where detection of various ...

Comammox Nitrospira contributed nitrification and N2O production activity in coastal wetland

2023
Specific nitrification inhibitors (NIs) have been widely used to disentangle the contribution of ammonia-oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB) as well as nitrite oxidizers to the nitrification process in specific environments. However, if these previously reported NIs can also be used to evaluate the activity of the newly discovered

Community structure and abundance of comammox Nitrospira in Chongming eastern intertidal sediments

Journal of Soils and Sediments, 2021
Complete ammonia oxidizers (comammox), which convert ammonia to nitrate through nitrite, are a newly discovered nitrifying group. In recent years, comammox Nitrospira have been discovered in various natural and engineered ecosystems. However, little is known about the distribution dynamics of comammox Nitrospira in estuary tidal flat sediments ...

Ubiquitous occurrence and functional dominance of comammox Nitrospira in full-scale wastewater treatment plants

Water Research, 2023
The recent discovery of complete ammonia oxidation (comammox) bacteria has fundamentally upended the traditional two-step nitrification conception, but their functional importance in wastewater treatment plants (WWTPs) is still poorly understood. This study investigated distributions of comammox Nitrospira, ammonia-oxidizing bacteria (AOB) and ammonia ...

[Research progress on primers and molecular ecology of comammox Nitrospira].

Ying yong sheng tai xue bao = The journal of applied ecology, 2021
Nitrification 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

2017
Vor 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 Nitrospira are the dominant ammonia oxidizers in the Yangtze estuarine biofilms

Water Research
Biofilms 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.

The functional dominance and metabolic diversity of comammox Nitrospira in recirculating aquaculture systems

Water Research
As a newly discovered group of ammonia-oxidizing microorganisms, complete ammonia oxidizing (comammox) Nitrospira has been widely found in various oligotrophic ecosystems. However, their activity and ecological niche is still unclear in recirculating aquaculture systems (RAS).

Comammox Nitrospira dominates the nitrification in artificial coniferous forest soils of the Qilian Mountains

Science of The Total Environment
Complete ammonia oxidizers (Comammox, CMX) are a newly discovered and important component of the nitrogen cycle. While CMX Nitrospira has been detected in various ecosystems, few studies so far have focused on the relative contribution and co-occurrence network of ammonia oxidizing archaea (AOA), bacteria (AOB), and CMX Nitrospira in artificial forest ...

Enrichment of comammox Nitrospira from three different seed sludges with addition of signaling molecules

Water Research
Complete ammonia oxidation (comammox) bacteria have been detected in full-scale wastewater treatment plants. However, the slow growth rate limits the research and applications of comammox. Quorum sensing (QS) is an intercellular communication process to regulate microbial physiological metabolism, but its role in comammox Nitrospira has rarely been ...
