Metagenomic Evidence for the Presence of Comammox
mSphere, 2016 We report metagenomic evidence for the presence of a Nitrospira-like organism with the metabolic potential to perform the complete oxidation of ammonia to nitrate (i.e., it is a complete ammonia oxidizer [comammox]) in a drinking water system.

Unraveling the important role of comammox Nitrospira to nitrification in the coastal aquaculture system [PDF]
Frontiers in MicrobiologyIncreasing nitrogen (N) input to coastal ecosystems poses a serious environmental threat. It is important to understand the responses and feedback of N removal microbial communities, particularly nitrifiers including the newly recognized complete ammonia-

AmoA-Targeted Polymerase Chain Reaction Primers for the Specific Detection and Quantification of Comammox Nitrospira in the Environment [PDF]
Frontiers in Microbiology, 2017 Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to be catalyzed by the concerted activity of ammonia- and nitrite-oxidizing microorganisms.

Nitrification inhibitor chlorate and nitrogen substrates differentially affect comammox Nitrospira in a grassland soil [PDF]
Frontiers in MicrobiologyIntroductionThrough the combined use of two nitrification inhibitors, Dicyandiamide (DCD) and chlorate with nitrogen amendment, this study aimed to investigate the contribution of comammox Nitrospira clade B, ammonia oxidizing bacteria (AOB) and archaea (

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “
mSystems, 2017 The recently discovered comammox bacteria have the potential to completely oxidize ammonia to nitrate. These microorganisms are part of the Nitrospira genus and are present in a variety of environments, including biological nutrient removal (BNR) systems.

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils [PDF]
Frontiers in Microbiology, 2020 In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape
EcosphereNitrification in terrestrial ecosystems is mediated by NH4+‐oxidizing bacteria (AOB) and archaea (AOA). Presently, we understand relatively little about how physiological capacities and environmental tolerances influence their community composition, and ...

Community assembly of comammox Nitrospira in coastal wetlands across southeastern China. [PDF]
Appl Environ Microbiol, 2023 ABSTRACT Complete ammonia oxidizers (comammox Nitrospira ) are ubiquitous in coastal wetland sediments and play an important role in nitrification. Our study examined the impact of habitat modifications on comammox Nitrospira communities in coastal wetland sediments across tropical ...

Metagenomic recovery of two distinct comammox Nitrospira from the terrestrial subsurface. [PDF]
Environ Microbiol, 2019 Summary The recently discovered comammox process encompasses both nitrification steps, the aerobic oxidation of ammonia and nitrite, in a single organism. All known comammox bacteria are affiliated with Nitrospira sublineage II and can be grouped into two distinct clades ...

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