Abundance, diversity and physiological preferences of comammox Nitrospira in urban groundwater

Science of The Total Environment, 2023
Complete ammonia oxidizer (comammox Nitrospira), catalyze complete nitrification process in a single organism, are frequently detected in groundwater ecosystem. However, the ecological niches and environmental driving factors of comammox Nitrospira in urban groundwater are largely unknown.

Ubiquity, diversity, and activity of comammox Nitrospira in agricultural soils

Science of The Total Environment, 2020
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-step nitrification model. However, the distribution and activity of comammox bacteria in various environments remain largely unknown.

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 ...

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.

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

Network of Nitrifying Bacteria in Aquarium Biofilters: An Unfaltering Cooperation Between Comammox Nitrospira and Ammonia-Oxidizing Archaea

Water (Switzerland)
Nitrification plays a crucial role in aquatic ecosystems and in the biofilters used in fish farms. Despite their importance, the role of canonical nitrifiers, comammox bacteria, and archaea has not yet been sufficiently investigated.

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).
