Isolation, cultivation, and characterization of ammonia-oxidizing bacteria and archaea adapted to low ammonium concentrations

, 2011
Ammonia-oxidizing microorganisms (AOM) generate their energy by the oxidation of ammonia (NH3) to nitrite (NO2−). This process can be carried out by ammonia-oxidizing bacteria (AOB) as well as by the recently discovered ammonia-oxidizing archaea (AOA ...

Soil Microbial Communities Changes Along Depth and Contrasting Facing Slopes at the Parque Nacional La Campana, Chile

Microorganisms
The Parque Nacional La Campana (PNLC) was recently recognized for its high soil surface microbial richness. Here, we explored the microbial community structure in soil profiles from contrasting facing slopes where sclerophyllous forest (SF) and ...

Searching for Ammonia-Oxidizing Archaea

, 2017
The Colorado River Basin runs through multiple states in the West of the United States and is a prime water source for about 30 million people in our nation and is used for much of the farmland and agricultural needs in this area.

Meta-analysis reveals ammonia-oxidizing bacteria respond more strongly to nitrogen addition than ammonia-oxidizing archaea [PDF]

, 2016
Shifts in microbial communities driven by anthropogenic nitrogen (N) addition have broad-scale ecological consequences. However, responses of microbial groups to exogenous N supply vary considerably across studies, hindering efforts to predict community ...

Abundance of Ammonia-Oxidizing Archaea and Bacteria along an Estuarine Salinity Gradient in Relationship to Potential Nitrification Rates

, 2009
Abundance of ammonia-oxidizing Archaea (AOA) was found to be always greater than that of ammonia-oxidizing Bacteria along an estuarine salinity gradient, and AOA abundance was highest at intermediate salinity.

Hydroxylamine released by nitrifying microorganisms is a precursor for HONO emission from drying soils

Scientific Reports, 2018
Nitrous acid (HONO) is an important precursor of the hydroxyl radical (OH), the atmosphere´s primary oxidant. An unknown strong daytime source of HONO is required to explain measurements in ambient air.

Snow Exclusion Does Not Affect Soil Ammonia-Oxidizing Bacteria and Archaea Communities

, 2022
Soil ammonia-oxidizing microorganisms play important roles in nitrogen (N) cycling in cold ecosystems, but how changes in snow cover will affect their distribution and associated functional characteristics remains unclear.

Vertical segregation and phylogenetic characterization of ammonia-oxidizing bacteria and archaea in the sediment of a freshwater aquaculture pond

Frontiers in Microbiology, 2016
Pond aquaculture is the major freshwater aquaculture method in China. Ammonia-oxidizing communities inhabiting pond sediments play an important role in controlling culture water quality.

Data from: Vascular plants mediate the effects of aridity and soil properties on ammonia-oxidizing bacteria and archaea

, 2013
An integrated perspective of the most important factors driving the abundance of ammonia-oxidizing bacteria (AOB) and archaea (AOA) in natural ecosystems is lacking, especially in drylands.

Benthic Ammonia Oxidizers Differ in Community Structure and Biogeochemical Potential Across a Riverine Delta

Frontiers in Microbiology, 2015
Nitrogen pollution in coastal zones is a widespread issue, particularly in ecosystems with urban or agricultural watersheds. California’s Sacramento-San Joaquin Delta, at the landward reaches of San Francisco Bay, is highly impacted by both agricultural ...
