Distribution and Diversity of Comammox Nitrospira in Coastal Wetlands of China [PDF]

open access: yesFrontiers in Microbiology, 2020
Complete ammonia oxidizers (comammox), able to individually oxidize ammonia to nitrate, are considered to play a significant role in the global nitrogen cycle.

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils [PDF]

open access: yesFrontiers 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 act as key bacteria in weakly acidic soil via potential cobalamin sharing

open access: yesiMeta
The discovery of comammox Nitrospira in low pH environments has reshaped the ammonia oxidation process in acidic settings, providing a plausible explanation for the higher nitrification rates observed in weakly acidic soils.

Unraveling the important role of comammox Nitrospira to nitrification in the coastal aquaculture system

open access: yesFrontiers in Microbiology
Increasing 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-

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape

open access: yesEcosphere
Nitrification 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 ...

Genomic profiling of Nitrospira species reveals ecological success of comammox Nitrospira

open access: yesMicrobiome, 2022
Background The discovery of microorganisms capable of complete ammonia oxidation to nitrate (comammox) has prompted a paradigm shift in our understanding of nitrification, an essential process in N cycling, hitherto considered to require both ammonia ...

Evolutionary Ecology of Natural Comammox Nitrospira Populations [PDF]

open access: yesmSystems, 2022
Microbes commonly exist in diverse and complex communities where species interact, and their genomic repertoires evolve over time. Our understanding of species interaction and evolution has increased during the last decades, but most studies of ...

Salinity changes the nitrification activity and community composition of comammox Nitrospira in intertidal sediments of Yangtze River estuary

open access: yesMSystems, 2023
The newly discovered complete ammonia-oxidizing (comammox) Nitrospira has been identified in different environments, including coastal environments, where salinity is one of the most important factors for the abundance and activity of nitrifiers.

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “Candidatus Nitrospira nitrosa” [PDF]

open access: yesmSystems, 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.

AmoA-Targeted Polymerase Chain Reaction Primers for the Specific Detection and Quantification of Comammox Nitrospira in the Environment

open access: yesFrontiers 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.
