Selective enrichment of comammox from activated sludge using antibiotics
Water Research, 2021While the ubiquitous presence of comammox in engineered systems provides the foundation of developing a novel biological nitrogen removal process, factors contributing to the comammox dynamics in engineered systems have not been well resolved. Here, we investigate the long-term effects of ten different antibiotics on microbial community dynamics in ...

Comammox in drinking water systems
Water Research, 2017The discovery of complete ammonia oxidizer (comammox) has fundamentally upended our perception of the global nitrogen cycle. Here, we reported four metagenome assembled genomes (MAGs) of comammox Nitrospira that were retrieved from metagenome datasets of tap water in Singapore (SG-bin1 and SG-bin2), Hainan province, China (HN-bin3) and Stanford, CA ...

In-situ expressions of comammox Nitrospira along the Yangtze River
Water Research, 2021The recent discovery of comammox Nitrospira as complete nitrifiers has significantly enriched our understanding on the nitrogen cycle, yet little is known about their metabolic transcripts in natural aquatic ecosystems. Using the genome-centric metatranscriptomics, we provided the first in-situ expression patterns of comammox Nitrospira along the ...

Comammox activity dominates nitrification process in the sediments of plateau wetland
Water Research, 2021The recent discovery of complete ammonia oxidation (comammox) has increased our understanding of nitrification. Although comammox has been shown to play an important role in plain wetland ecosystems, studies of comammox contribution are still limited in plateau wetland ecosystems.

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, 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.

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).

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.

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.
