Diversity distribution and characteristics of comammox in different ecosystems
Environmental Research, 2022The discovery of complete ammonia oxidizers (comammox), which can oxidize ammonia into nitrate, has recently changed the concept of traditional nitrification. However, comparative studies on the analysis of comammox microbial community in different ecosystems are still scarce.

Ubiquity and Diversity of Complete Ammonia Oxidizers (Comammox) [PDF]
Applied and Environmental Microbiology, 2018 The discovery of complete ammonia oxidizers (comammox), which oxidize ammonia to nitrate via nitrite, refutes the century-old paradigm that nitrification requires the activity of two types of microbes and redefines a key process in the biogeochemical nitrogen cycle.

Ubiquity, diversity, and activity of comammox Nitrospira in agricultural soils
Science of the Total Environment, 2020The 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.

Ecological distribution and function of comammox Nitrospira in the environment
Applied Microbiology and Biotechnology, 2023Complete ammonia oxidizers (Comammox) are of great significance for studying nitrification and expanding the understanding of the nitrogen cycle. Moreover, Comammox bacteria are also crucial in natural and engineered environments due to their role in wastewater treatment and maintaining the flux of greenhouse gases to the atmosphere.

Biogeographic distribution of comammox bacteria in diverse terrestrial habitats
Science of The Total Environment, 2020Comammox, the microbial group capable of completely oxidizing ammonia to nitrate, challenged the traditional two-step nitrification process where ammonia is oxidized by ammonia-oxidizing archaea (AOA) and bacteria (AOB), and nitrite by nitrite-oxidizing bacteria (NOB).

Competitive enrichment of comammox Nitrospira in floccular sludge
Water ResearchThe 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 ...

The long-term effects of using nitrite and urea on the enrichment of comammox bacteria
Science of the Total Environment, 2021The discovery of complete ammonia oxidizer (comammox) was a breakthrough in the study of nitrification. However, slow growth of comammox bacteria makes it challenging to distinguish them from traditional ammonia oxidizing microorganisms. Genomic data indicated that comammox bacteria encoded genes that can metabolize urea and had higher nitrite ...

Comammox Nitrospira clade B contributes to nitrification in soil
Soil Biology and Biochemistry, 2019Abstract 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.
