Niche specialization of comammox Nitrospira clade A in terrestrial ecosystems

Soil Biology and Biochemistry, 2021
Comammox Nitrospira are a newly discovered group of nitrifying prokaryotes and might be key contributors to nitrogen cycling in terrestrial ecosystems. Their large-scale distribution patterns and the dominant environmental factors shaping their ecological niches are not yet well documented.

Specific Micropollutant Biotransformation Pattern by the Comammox Bacterium Nitrospira inopinata

Environmental Science & Technology, 2019
The 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 ...

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 clade B contributes to nitrification in soil

Soil Biology and Biochemistry, 2019
Abstract Comammox, one nitrifying microorganism carries out the complete oxidation of ammonia to nitrate, have been recently discovered, and are found in a wide range of environments, including soil. However, conditions under which they actually contribute to nitrification in soil have not yet been demonstrated.

Efficient conversion of organic nitrogenous wastewater to nitrate solution driven by comammox Nitrospira

Water Research, 2021
A bacterium capable of complete ammonia oxidation (comammox) has been widely found in various environments, whereas its industrial application is limited due to the difficulty of cultivation and/or enrichment. We developed a biological system to produce a high-quality nitrate solution for use in hydroponic fertilizer.

[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.

Niche adaptation strategies of different clades of comammox Nitrospira in the Yangtze Estuary

International Biodeterioration & Biodegradation, 2021
Abstract The discovery of complete ammonia oxidizers (comammox) changed the conventional view of the previously known two-step process of nitrification. Comammox Nitrospira that can independently oxidize ammonia to nitrate have been found existing in various ecosystems except the ocean.

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.

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
