Complete nitrification: insights into the ecophysiology of comammox Nitrospira. [PDF]

Appl Microbiol Biotechnol, 2019
Nitrification, the oxidation of ammonia via nitrite to nitrate, has been considered to be a stepwise process mediated by two distinct functional groups of microorganisms. The identification of complete nitrifying Nitrospira challenged not only the paradigm of labor division in nitrification, it also raises fundamental questions regarding the ...

Niche differentiation among comammox (Nitrospira inopinata) and other metabolically distinct nitrifiers. [PDF]

Front Microbiol, 2022
Due to global change, increasing nutrient input to ecosystems dramatically affects the nitrogen cycle, especially the nitrification process. Nitrifiers including ammonia-oxidizing archaea (AOAs), ammonia-oxidizing bacteria (AOBs), nitrite-oxidizing bacteria (NOBs), and recently discovered complete ammonia oxidizers (comammoxs) perform nitrification ...

Nutrient-Limited Enrichments of Nitrifiers From Soil Yield Consortia of Nitrosocosmicus-Affiliated AOA and Nitrospira-Affiliated NOB

Frontiers in Microbiology, 2021
The discovery of ammonia-oxidizing archaea (AOA) and complete ammonia-oxidizing (comammox) bacteria widespread in terrestrial ecosystems indicates an important role of these organisms in terrestrial nitrification.

Comammox Nitrospira within the Yangtze River continuum: community, biogeography, and ecological drivers. [PDF]

ISME J, 2020
Abstract The recent discovery of comammox Nitrospira as complete nitrifiers has fundamentally renewed perceptions of nitrogen cycling in natural and engineered systems, yet little is known about the environmental controls on these newly recognized bacteria.

An investigation of Nitrospira bacteria in coastal wetlands of China: distribution pattern and related environmental driving factors

Frontiers in Marine Science, 2023
Nitrate is mainly converted via aerobic nitrite oxidation during the second step of nitrification, which is catalyzed by nitrite-oxidizing bacteria (NOB) and the recently discovery complete ammonia oxidizers (comammox).

Activity and Metabolic Versatility of Complete Ammonia Oxidizers in Full-Scale Wastewater Treatment Systems

mBio, 2020
The recent discovery of complete ammonia oxidizers (comammox) contradicts the paradigm that chemolithoautotrophic nitrification is always catalyzed by two different microorganisms.
