Global Occurrence of Archaeal amoA Genes in Terrestrial Hot Springs [PDF]

open access: yesApplied and Environmental Microbiology, 2008
ABSTRACT Despite the ubiquity of ammonium in geothermal environments and the thermodynamic favorability of aerobic ammonia oxidation, thermophilic ammonia-oxidizing microorganisms belonging to the crenarchaeota kingdom have only recently been described.

Reduction in N2O Emissions and Improvement in Nitrifier and Denitrifier Communities through Bamboo-Biochar-Based Fertilization in Pomelo Orchard Soil

open access: yesAgronomy, 2023
Farmland soil is an important source of the greenhouse gas nitrous oxide (N2O), and soil nitrification and denitrification are key processes affecting N2O production.

amoA ‐based consensus phylogeny of ammonia‐oxidizing archaea and deep sequencing of amoA genes from soils of four different geographic regions [PDF]

open access: yesEnvironmental Microbiology, 2011
Summary Ammonia‐oxidizing archaea (AOA) play an important role in nitrification and many studies exploit their amoA genes as marker for their diversity and abundance. We present an archaeal amoA consensus phylogeny based on all ...

Niche differentiation of comammox Nitrospira in sediments of the Three Gorges Reservoir typical tributaries, China

open access: yesScientific Reports, 2022
Complete ammonia oxidizer (Comammox) can complete the whole nitrification process independently, whose niche differentiation is important guarantee for its survival and ecological function.

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

open access: yesFrontiers 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. PCR-based approach, a common method for the detection of comammox, depends strongly on accurate amplification of the amoA genes from the original DNA samples ...

Diversity of Archaea and detection of crenarchaeotal amoA genes in the rivers Rhine and Têt [PDF]

open access: yesAquatic Microbial Ecology, 2009
Pelagic archaeal phylogenetic diversity and the potential for crenarchaeotal nitrification of Group 1.1a were determined in the rivers Rhine and Tet by 16S rRNA sequencing, catalyzed reported deposition-fluorescence in situ hybridization (CARD–FISH) and quantification of 16S rRNA and functional genes. Euryarchaeota were, for the first time, detected in

Biochar Addition Inhibits Nitrification by Shifting Community Structure of Ammonia-Oxidizing Microorganisms in Salt-Affected Irrigation-Silting Soil

open access: yesMicroorganisms, 2022
Biochar has been widely recognized as an effective and eco-friendly ameliorant for saline soils, but information about the mechanism of how biochar influences nitrification in salt-affected agroecosystem remains fragmented.

Ammonia oxidizers in the sea-surface microlayer of a coastal marine inlet. [PDF]

open access: yesPLoS ONE, 2018
Planktonic archaea are thought to play an important role in ammonia oxidation in marine environments. Data on the distribution, abundance, and diversity of ammonia oxidizers in the coastal sea-surface microlayer (SML) are lacking, despite previous ...

Primer evaluation and development of a droplet digital PCR protocol targeting amoA genes for the quantification of Comammox in lakes [PDF]

open access: yesScientific Reports, 2021
AbstractTo date, little is known about the ecological significance of Comammox (COMplete AMMonia OXidizers) Nitrospira in the water column of freshwater lakes. Water samples collected along depth profiles were used to investigate the distribution of Comammox in 13 lakes characterized by a wide range of physicochemical properties.
