Evolutionary Ecology of Natural Comammox Nitrospira Populations [PDF]
mSystems, 2022 Microbes commonly exist in diverse and complex communities where species interact, and their genomic repertoires evolve over time. Our understanding of species interaction and evolution has increased during the last decades, but most studies of ...

Evaluation of four primer sets for analysis of comammox communities in black soils
Frontiers in Microbiology, 2022 Comammox, as a newly discovered ammonia oxidizer, urgently needs highly efficient and specific primers to detect its community structure and diversity. In this study, the performance of widely used primer set Ntsp-amoA 162F/359R and newly designed primer

Design and Assessment of Species-Level qPCR Primers Targeting Comammox [PDF]
Frontiers in Microbiology, 2019 Published PCR primers targeting the ammonia monooxygenase gene (amoA) were applied to samples from activated sludge systems operated with low dissolved oxygen (DO) to quantify total and clade-level Nitrospira that perform complete ammonium oxidation ...

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils [PDF]
Frontiers in Microbiology, 2020 In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape
EcosphereNitrification 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 ...

Unveiling unique microbial nitrogen cycling and nitrification driver in coastal Antarctica [PDF]
Nature CommunicationsLargely 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 ...

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