Temporal enrichment of comammox Nitrospira and Ca. Nitrosocosmicus in a coastal plastisphere. [PDF]

ISME J
Abstract Plastic marine debris is known to harbor a unique microbiome (termed the “plastisphere”) that can be important in marine biogeochemical cycles. However, the temporal dynamics in the plastisphere and their implications for marine biogeochemistry remain poorly understood.

Niche specialization of comammox Nitrospira in terrestrial ecosystems: Oligotrophic or copiotrophic?

Critical Reviews in Environmental Science and Technology, 2022
The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a breakthrough in the history of nitrification research. Nitrospira inopinata, which was obtained from an aquatic ecosystem, is the only pure comammox bacterial isolate reported so far. Ammonia oxidation kinetics of N.

Comparative genomics sheds light on niche differentiation and the evolutionary history of comammox Nitrospira. [PDF]

ISME J, 2018
Abstract The description of comammox Nitrospira spp., performing complete ammonia-to-nitrate oxidation, and their co-occurrence with canonical β-proteobacterial ammonia oxidizing bacteria (β-AOB) in the environment, calls into question the metabolic potential of comammox Nitrospira and the evolutionary history of their ammonia ...

Soil Moisture is a Primary Driver of Comammox Nitrospira Abundance in New Zealand Soils

SSRN Electronic Journal, 2022
The objectives of this study were to investigate the abundance and community composition of comammox Nitrospira under: (i) pasture-based dairy farms from different regions, and (ii) different land uses from the same region and soil type. The results clearly showed that comammox Nitrospira were most abundant (3.0 × 106 copies) under the west coast dairy

Growth of comammox Nitrospira is inhibited by nitrification inhibitors in agricultural soils [PDF]

Journal of Soils and Sediments, 2019
Purpose: The discovery of comammox Nitrospira being capable of complete oxidising ammonia to nitrate radically challenged the conventional concept of two-step nitrification. However, the response of comammox Nitrospira to nitrification inhibitors (NIs) and their role in soil nitrification remain largely unknown, which has hindered our ability to ...

The environmental detection of comammox Nitrospira

, 2017
Vor kurzem wurden die ersten Mikroorganismen entdeckt, die in der Lage sind Ammonium komplett zu Nitrat zu oxidieren (‘comammox’), und dadurch das Dogma, über die Arbeitsteilung in der Nitrifikation in zwei aufeinanderfolgenden Schritten, für ungültig erklärt.

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.

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

Competitive enrichment of comammox Nitrospira in floccular sludge

Water Research
The discovery of complete ammonium oxidation (comammox) has subverted the traditional perception of two-step nitrification, which plays a key role in achieving biological nitrogen removal from wastewater. Floccular sludge-based treatment technologies are being applied at the majority of wastewater treatment plants in service where detection of various ...

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
