Diversity, Physiology, and Niche Differentiation of Ammonia-Oxidizing Archaea [PDF]

, 2012
Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to have been a central part of the global biogeochemical nitrogen cycle since the oxygenation of Earth.

Nitrifier Gene Abundance and Diversity in Sediments Impacted by Acid Mine Drainage

Frontiers in Microbiology, 2017
Extremely acidic and metal-rich acid mine drainage (AMD) waters can have severe toxicological effects on aquatic ecosystems. AMD has been shown to completely halt nitrification, which plays an important role in transferring nitrogen to higher organisms ...

Response of Nitrification and Crop Yield to the Presence of NBPT and DCD in a Wheat-Corn Double Cropping System

Agronomy
The excessive application of nitrogen fertilizer aggravated the loss of nitrogen in farmland and exerted detrimental effects on the soil and water environment. Examining the effects of N-(n-Butyl)thiophosphoric triamide (NBPT) and nitrification inhibitor

Diversity and mode of transmission of ammonia-oxidizing archaea in marine sponges

, 2008
The model marine crenarchaeote ‘Cenarchaeum symbiosum’ is until now the only ammonia-oxidizing archaeon known from a marine sponge. Here, phylogenetic analyses based on the 16S rRNA and ammonia monooxygenase subunit A (amoA) genes revealed the presence ...

Evolution of ammonia-oxidizing archaea related to global events

, 2020
Ammonia-oxidizing archaea (AOA) are chemolithoautotrophs that dominate nitrification in today's low ammonium ocean, playing critical roles in the global nitrogen cycle, alongside ammonia-oxidizing bacteria (AOB) that favor higher ammonium environments ...

Effects of Zeolite and Biochar Addition on Ammonia-Oxidizing Bacteria and Ammonia-Oxidizing Archaea Communities during Agricultural Waste Composting

, 2020
The effects of zeolite and biochar addition on ammonia-oxidizing bacteria (AOB) and archaea (AOA) communities during agricultural waste composting were determined in this study.

Ammonia-oxidizing archaea in engineered biofiltration systems

, 2016
Ammonia is a nitrogenous metabolic waste product that is produced by all animal life. High concentrations of ammonia are toxic to animals and may result in algal blooms and eutrophication in aquatic environments. To prevent negative impacts on animal and

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape

Ecosphere
Nitrification in terrestrial ecosystems is mediated by NH4+‐oxidizing bacteria (AOB) and archaea (AOA). Presently, we understand relatively little about how physiological capacities and environmental tolerances influence their community composition, and ...

The hidden potential of archaea in carbon and nitrogen cycling in agricultural soils: a review

Frontiers in Microbiology
The soil microbiome drives soil nutrient cycling and is intrinsically linked to plant productivity in agriculture. Archaea are members of many soil microbiomes and play important roles in nutrient cycling, particularly in the carbon and nitrogen cycle ...
