Linking 16S rRNA Gene Classification to amoA Gene Taxonomy Reveals Environmental Distribution of Ammonia-Oxidizing Archaeal Clades in Peatland Soils [PDF]

mSystems, 2021
A highly resolved taxonomy for ammonia-oxidizing archaea (AOA) based on the alpha subunit of ammonia monooxygenase (amoA) was recently established, which uncovered novel environmental patterns of AOA, challenging previous generalizations.

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary. [PDF]

Environ Microbiol
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Can Organic Amendments Override Environmental Filtering of Soil Microbiomes? Evidence From 20 Years Old Agricultural Field Trials in Contrasting Tropical Sites. [PDF]

Glob Chang Biol
Across four long‐term Kenyan maize trials, site was the dominant driver of microbial community composition and N‐cycling gene abundance. Among organic amendments, farmyard manure most strongly enriched copiotrophic taxa and raised prokaryotic diversity.

Synergistic effects of AWD irrigation and potassium application on rice yield and paddy field greenhouse gas emissions [PDF]

Frontiers in Plant Science
IntroductionIrrigation and fertilization are significant for rice productivity and environmental benefits. Evidences on how alternate wetting-drying irrigation (IAWD) and potassium (K) together influence greenhouse gas emission (GHG) and rice yield still

Nitrogen addition altered the microbial functional potentials of carbon and nitrogen transformation in alpine steppe soils on the Tibetan Plateau

Global Ecology and Conservation, 2021
The microbial-mediated functional potentials of soil can be reflected by the abundance of corresponding microbial functional genes (MFGs). Few studies have simultaneously examined the responses of multiple key MFGs involving soil carbon (C) and nitrogen (

Temperature responses of ammonia-oxidizing prokaryotes in freshwater sediment microcosms. [PDF]

PLoS ONE, 2014
In order to investigate the effects of temperature on the abundances and community compositions of ammonia-oxidizing archaea (AOA) and bacteria (AOB), lake microcosms were constructed and incubated at 15°C, 25°C and 35°C for 40 days, respectively ...

Diversity and distribution of amoA-type nitrifying and nirS-type denitrifying microbial communities in the Yangtze River estuary [PDF]

Biogeosciences, 2014
Coupled nitrification–denitrification plays a critical role in the removal of excess nitrogen, which is chiefly caused by humans, to mitigate estuary and coastal eutrophication.

Saline and alkaline stresses alter soil properties and composition and structure of gene-based nitrifier and denitrifier communities in a calcareous desert soil

BMC Microbiology, 2021
Background Saline and alkaline stresses damages the health of soil systems. Meanwhile, little is known about how saline or alkaline stress affects soil nitrifier and denitrifier communities.

Aquarium nitrification revisited: Thaumarchaeota are the dominant ammonia oxidizers in freshwater aquarium biofilters. [PDF]

PLoS ONE, 2011
Ammonia-oxidizing archaea (AOA) outnumber ammonia-oxidizing bacteria (AOB) in many terrestrial and aquatic environments. Although nitrification is the primary function of aquarium biofilters, very few studies have investigated the microorganisms ...
