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.

Exploring Suitable Nitrification Inhibitor in an Intensively Cultivated Greenhouse Soil and Its Effect on the Abundance and Community of Soil Ammonia Oxidizers

Agronomy
The application of nitrification inhibitors (NIs) is an effective way to reduce soil nitrogen (N) losses and increase crop N uptake. Yet, the efficacy of NIs commonly varies with dosages, crop systems and soil environmental conditions.

Unveiling unique microbial nitrogen cycling and nitrification driver in coastal Antarctica

Nature Communications
Largely removed from anthropogenic delivery of nitrogen (N), Antarctica has notably low levels of nitrogen. Though our understanding of biological sources of ammonia have been elucidated, the microbial drivers of nitrate (NO3 −) cycling in coastal ...

Comparative enrichment of complete ammonium oxidation bacteria in floccular sludge reactors: Sequencing batch reactor vs. continuous stirred tank reactor

Water Research X
This study attempted to compare the enrichment of complete ammonium oxidation (comammox) bacteria, which are affiliated with Nitrospira and not able to generate nitrous oxide (N2O, a potent greenhouse gas) through biological pathways, in two commonly ...

Functional redundancy and niche complementarity maintain nitrification stability in rapid sand filters

Frontiers in Microbiology
Nitrification in drinking water biofilters is mediated by a complex guild of ammonia oxidizers, yet the mechanisms facilitating the coexistence of these functionally redundant nitrifier guild members are not well understood.
