Evaluation of four primer sets for analysis of comammox communities in black soils
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

Evolutionary Ecology of Natural Comammox Nitrospira Populations [PDF]
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 ...

Design and Assessment of Species-Level qPCR Primers Targeting Comammox [PDF]
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]
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 ...

Nitrogen source influences the interactions of comammox bacteria with aerobic nitrifiers
While the co-existence of comammox Nitrospira with canonical nitrifiers is well documented in diverse ecosystems, there is still a dearth of knowledge about the mechanisms underpinning their interactions.

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “
The recently discovered comammox bacteria have the potential to completely oxidize ammonia to nitrate. These microorganisms are part of the Nitrospira genus and are present in a variety of environments, including biological nutrient removal (BNR) systems.

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

Complete nitrification: insights into the ecophysiology of comammox Nitrospira [PDF]
Nitrification, the oxidation of ammonia via nitrite to nitrate, has been considered to be a stepwise process mediated by two distinct functional groups of microorganisms. The identification of complete nitrifying Nitrospira challenged not only the paradigm of labor division in nitrification, it also raises fundamental questions regarding the ...

Diversity and abundance of comammox bacteria in the sediments of an urban lake [PDF]
Although comammox have been discovered in a variety of ecosystems, there are few studies in urban lakes. This paper attempted to confirm whether this ammonia-oxidizing microbe exists in urban lakes and to determine the factors influencing its existence.This study investigated the diversity and abundance of comammox bacteria in sediments of a typical ...
