Niche specialization of comammox Nitrospira in terrestrial ecosystems: Oligotrophic or copiotrophic?
Critical Reviews in Environmental Science and Technology, 2022 The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a breakthrough in the history of nitrification research. Nitrospira inopinata, which was obtained from an aquatic ecosystem, is the only pure comammox bacterial isolate reported so far. Ammonia oxidation kinetics of N.

Ammonia-oxidizing archaea and complete ammonia-oxidizing Nitrospira in water treatment systems
Water Research X, 2022 Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered water treatment systems. The sequential steps of this respiratory process are carried out by distinct microbial guilds, including ammonia-oxidizing bacteria (

Cyclic Conversions in the Nitrogen Cycle
Frontiers in Microbiology, 2021 The cyclic nature of specific conversions in the nitrogen cycle imposes strict limitations to the conversions observed in nature and explains for example why anaerobic ammonium oxidation (anammox) bacteria can only use nitrite – and not nitrate – as ...

Metagenomic recovery of two distinct comammox Nitrospira from the terrestrial subsurface [PDF]
Environmental Microbiology, 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 ...

Soil Moisture is a Primary Driver of Comammox Nitrospira Abundance in New Zealand Soils
SSRN Electronic Journal, 2022 The objectives of this study were to investigate the abundance and community composition of comammox Nitrospira under: (i) pasture-based dairy farms from different regions, and (ii) different land uses from the same region and soil type. The results clearly showed that comammox Nitrospira were most abundant (3.0 × 106 copies) under the west coast dairy

Existence and distribution of novel phylotypes of Nitrospira in water columnsof the South China Sea
iScience, 2022 Summary: In the biological nitrogen cycle, nitrite oxidation is performed by nitrite oxidation bacteria, of which Nitrospira is widespread and diverse. Communities of Nitrospira were collected at 25–1500 m depths in the South China Sea.

Growth of comammox Nitrospira is inhibited by nitrification inhibitors in agricultural soils [PDF]
Journal of Soils and Sediments, 2019 Purpose: The discovery of comammox Nitrospira being capable of complete oxidising ammonia to nitrate radically challenged the conventional concept of two-step nitrification. However, the response of comammox Nitrospira to nitrification inhibitors (NIs) and their role in soil nitrification remain largely unknown, which has hindered our ability to ...

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

Frontiers in Microbiology, 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 ...
