Dominance of comammox Nitrospira in soil nitrification
Science of The Total Environment, 2021The first and limiting step of nitrification is catalyzed by ammonia-oxidizing archaea (AOA) and bacteria (AOB). Recently, complete ammonia oxidizers (comammox Nitrospira) have been discovered to perform complete nitrification in one cell, yet their role in soil nitrification is still unclear.

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 ...

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.

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.

Specific Micropollutant Biotransformation Pattern by the Comammox Bacterium Nitrospira inopinata
Environmental Science & Technology, 2019The 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 ...

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.

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.
