Genomic profiling of Nitrospira species reveals ecological success of comammox Nitrospira [PDF]
, 2019 Abstract Nitrification was long thought to consist in the stepwise oxidation of ammonia to nitrite and of nitrite to nitrate by ammonia oxidizing and nitrite oxidizing microorganisms, respectively. Recently, single microorganisms capable of complete ammonia to nitrate oxidation (comammox) were identified in the

Comammox Nitrospira are abundant ammonia oxidizers in diverse groundwater‐fed rapid sand filter communities [PDF]
, 2018 The recent discovery of completely nitrifying Nitrospira demands a re‐examination of nitrifying environments to evaluate their contribution to nitrogen cycling. To approach this challenge, tools are needed to detect and quantify comammox Nitrospira.

Frontiers in Microbiology, 2021 Autotrophic nitrification is regulated by canonical ammonia-oxidizing archaea (AOA) and bacteria (AOB) and nitrite-oxidizing bacteria (NOB). To date, most studies have focused on the role of canonical ammonia oxidizers in nitrification while neglecting ...

Sustained nitrogen loss in a symbiotic association of Comammox Nitrospira and Anammox bacteria [PDF]
Water Research, 2020 ABSTRACT The discovery of complete aerobic and anaerobic ammonia-oxidizing bacteria (Comammox and Anammox) significantly altered our understanding of the global nitrogen cycle. A high affinity for ammonia ( K m(app),NH3 ≈ 63nM) and oxygen place the first described ...

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 (

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.

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 ...
