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

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape
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
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]
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 ...

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “
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.
