Dramatic loss of comammox Nitrospira associated with long-term nitrite feeding [PDF]

, 2017
Until recently, nitrification was thought to be a strict two-step process where ammonia was first oxidized to nitrite by ammonia-oxidizing bacteria and/or archaea, and subsequently to nitrate by nitrite oxidizing bacteria (NOB).

Apparent contribution of complete ammonia-oxidizing organisms (comammox) to the global nitrogen cycle highlights the necessity for understanding niche differentiation of comammox bacteria among other ammonia oxidizers. While the high affinity for ammonia

Conversion of coastal marsh to aquaculture ponds altered soil ammonia oxidiser community and decreased ammonia oxidation potential

Journal of Sustainable Agriculture and Environment, Volume 3, Issue 3, September 2024.
Abstract Introduction As a crucial component of the nitrogen cycle, ammonia oxidation in soil can be driven by canonical ammonia‐oxidising archaea (AOA) and bacteria, as well as complete ammonia oxidiser (CMX Nitrospira). Land use change can disrupt and alter the soil microbial community and the nitrogen cycle.

Enrichment and activity of comammox Nitrospira from the rotating biological contactors of a municipal wastewater treatment system [PDF]

, 2021
Nitrification, the biological conversion of ammonia to nitrate, via nitrite, is an important process in both natural and engineered systems. Nitrification within wastewater treatment plants (WWTPs) is necessary because elevated ammonia concentrations are

Impact of nitrapyrin on urea‐based fertilizers in a Mediterranean calcareous soil: Nitrogen and microbial dynamics

European Journal of Soil Science, Volume 75, Issue 4, July–August 2024.
Abstract Nitrification inhibitors, such as nitrapyrin (NI), are increasingly co‐applied with nitrogen (N) fertilizers as part of sustainable agricultural practice. Several studies in temperate regions have documented the effectiveness of NI in retaining soil ammonium (NH4+), minimizing N loss and increasing crop yields. However, less is known about the

Table_1_Unraveling the important role of comammox Nitrospira to nitrification in the coastal aquaculture system.docx

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 are key nitrifiers in diverse groundwater-fed drinking water filters [PDF]

, 2017
Nitrification is a dominant process in groundwater-fed rapid sand filters (RSFs) used for drinking water purification. Near complete removal of ammonium and nitrite is required in the EU and Denmark due to strict regulatory limits that enable high water ...

Evaluation of the process performance of comammox-like nitrospira dominant down-flow hanging sponge reactor with reduced nitrous oxide emissions

Water Research X
Nitrification/denitrification mitigates excess nitrogen in wastewater and reduces nutrient pollution in recipient surface waters but emits substantial amounts of nitrous oxide (N₂O).

Comprehensive evaluation of primer pairs targeting the ammonia monooxygenase subunit A gene of complete ammonia-oxidizing Nitrospira

Microbiology Spectrum
Since the discovery of complete ammonia oxidizers (comammox) within the genus Nitrospira, their distribution and abundance across habitats have been intensively studied to better understand their ecological significance.
