ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea

open access: yes, 2001
Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.

Diversity and abundance of ammonia-oxidizing archaea in the Dongjiang River, China

open access: yesMicrobiological Research, 2011
Nitrification in aquatic ecosystems plays a crucial role in the global nitrogen cycling. It has been widely accepted that ammonia-oxidizing bacteria (AOB) are responsible for nitrification. However, this concept is currently challenged by the ubiquity of ammonia-oxidizing archaea (AOA) in various environments, such as in aquatic and terrestrial ...

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

open access: yesFrontiers 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 ...

Diversity and community structure of ammonia oxidizing archaea in long term fertilized paddy fields

open access: yes, 2017
Long-term experiments involving different fertilization practices have been conducted at Miryang research station, South Korea since 1967 for the purpose of studying how varying fertilization regimes influence soil parameters and crop yield. By utilizing

Membraneless channels sieve cations in ammonia-oxidizing marine archaea.

open access: yes
Nitrosopumilus maritimus is an ammonia-oxidizing archaeon that is crucial to the global nitrogen cycle1,2. A critical step for nitrogen oxidation is the entrapment of ammonium ions from a dilute marine environment at the cell surface and their subsequent

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

open access: yesAgronomy
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

Evolution of ammonia-oxidizing archaea related to global events

open access: yes, 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 ...

Ammonia-oxidizing archaea in engineered biofiltration systems

open access: yes, 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
