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 ...

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.

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 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 ...

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 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.

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.

Abundance, diversity and physiological preferences of comammox Nitrospira in urban groundwater
Science of The Total Environment, 2023Complete 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.

Niche specialization of comammox Nitrospira clade A in terrestrial ecosystems
Soil Biology and Biochemistry, 2021Abstract 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.

Comammox bacterial abundance, activity, and contribution in agricultural rhizosphere soils
Science of The Total Environment, 2020The newly identified complete ammonia oxidation (comammox), which is capable of oxidizing ammonia directly to nitrate, has complemented our knowledge of nitrification in the global nitrogen (N) cycle. However, understanding the contribution and ecological roles of comammox in complex soil environments is still in its infancy.
