Evaluation of Two Primer Sets for Amplification of Comammox Nitrospira amoA Genes in Wetland Soils [PDF]

Frontiers in Microbiology, 2020
After the discovery of complete ammonia-oxidizing (comammox) Nitrospira, detection and assessments of the contribution of comammox Nitrospira communities to nitrogen cycling are in great demand.

The Genomic Potentials of NOB and Comammox Nitrospira in River Sediment Are Impacted by Native Freshwater Mussels [PDF]

Frontiers in Microbiology, 2018
Freshwater mussel assemblages of the Upper Mississippi River (UMR) sequester tons of ammonia- and urea-based biodeposits each day and aerate sediment through burrowing activities, thus creating a unique niche for nitrogen (N) cycling microorganisms. This

Hot spring distribution and survival mechanisms of thermophilic comammox Nitrospira. [PDF]

ISME J, 2023
Abstract The recent discovery of Nitrospira species capable of complete ammonia oxidation (comammox) in non-marine natural and engineered ecosystems under mesothermal conditions has changed our understanding of microbial nitrification.

Ammonium Removal in Aquaponics Indicates Participation of Comammox Nitrospira. [PDF]

Curr Microbiol, 2021
AbstractAquaponic systems are sustainable solutions for food production combining fish growth (aquaculture) and production of vegetables (hydroponic) in one recirculating system. In aquaponics, nitrogen-enriched wastewater from fish in the aquaculture serves as fertilizer for the plants in the hydroponics, while the nitrogen-depleted and detoxified ...

Competitive and substrate limited environments drive metabolic heterogeneity for comammox Nitrospira. [PDF]

ISME Commun, 2023
Abstract Nitrospira has been revealed as a high versatile genus. Although previously considered only responsible for the conversion of nitrite to nitrate, now we know that Nitrospira can perform complete ammonia oxidation to nitrate too (comammox).

Photoinhibition of comammox reaction in Nitrospira inopinata in a dose- and wavelength-dependent manner

Frontiers in Microbiology, 2022
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

Community assembly of comammox Nitrospira in coastal wetlands across southeastern China. [PDF]

Appl Environ Microbiol, 2023
ABSTRACT Complete ammonia oxidizers (comammox Nitrospira ) are ubiquitous in coastal wetland sediments and play an important role in nitrification. Our study examined the impact of habitat modifications on comammox Nitrospira communities in coastal wetland sediments across tropical ...

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

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.
