Comammox Nitrospira are abundant ammonia oxidizers in diverse groundwater‐fed rapid sand filter communities [PDF]

Environmental Microbiology, 2018
Summary The recent discovery of completely nitrifying Nitrospira demands a re‐examination of nitrifying environments to evaluate their contribution to nitrogen cycling.

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape

Ecosphere
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 ...

Component Microenvironments and System Biogeography Structure Microorganism Distributions in Recirculating Aquaculture and Aquaponic Systems [PDF]

, 2019
Flowthrough and pond aquaculture system microbiome management practices aim to mitigate fish disease and stress. However, the operational success of recirculating aquaculture systems (RAS) depends directly on system microbial community activities. In RAS,

Compound drought-heat legacies promote the contribution of comammox Nitrospira to N2O emissions: as evidenced from both acidic and alkaline soils

Geoderma
The responses of complete ammonia oxidization (comammox) to compound drought and heat and their contributions to post-drought nitrous oxide (N2O) emissions remain unclear.

Optimization of Nitrogen Removal Rate in One-Stage Reactor through Partial Nitrification Anammox Process during Direct Treatment of Poultry Litter Wastewater [PDF]

, 2021
Anammox is an increasingly common process used for the treatment of reject water and even mainstream wastewater due to its low oxygen demand. However, anammox is not commonly utilized in the direct treatment of poultry litter because of the high organic ...

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).
