The production of nitric oxide by marine ammonia‐oxidizing archaea and inhibition of archaeal ammonia oxidation by a nitric oxide scavenger

Environmental Microbiology, 2015
Summary Nitrification is a critical process for the balance of reduced and oxidized nitrogen pools in nature, linking mineralization to the nitrogen loss processes of denitrification and anammox. Recent studies indicate a significant contribution of ammonia‐oxidizing archaea ( AOA

Diversity and Abundance of Ammonia-Oxidizing Bacteria and Ammonia-Oxidizing Archaea During Cattle Manure Composting

Microbial Ecology, 2010
Ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) play important roles in nitrification in various environments. They may also be key communities for ammonia oxidation in composting systems, although few studies have discussed their presence. We investigated the relative diversity and abundance of AOB and AOA using cloning procedures,

Ammonia-oxidizing activity and microbial structure of ammonia-oxidizing bacteria, ammonia-oxidizing archaea and complete ammonia oxidizers in biofilm systems with different salinities

Bioresource Technology
Ammonia-oxidizing activity of different ammonia-oxidizing microorganisms (AOMs), such as ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and complete ammonia oxidizers (comammoxs), were investigated by adding the inhibitors such as 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide, octyne, and KCLO3 in biofilm systems with ...

Characterization of ammonia-oxidizing archaea by Raman microspectroscopy

2012
Nitrifikation ist die Oxidation von Ammonium zu Nitrit und weiter zu Nitrat. Es ist einer der wichtigsten Schritte im globalen Stickstoffkreislauf. Für lange Zeit glaubte man, dass für den ersten Schritt der Nitrifikation ausschließlich Ammoniak-oxidierende Bakterien (AOB) verantwortlich sind, jedoch wurden vor einigen Jahren die Ammoniak-oxidierenden ...

Towards a genetic system for ammonia oxidizing archaea

Ammonia oxidizing archaea (AOA) play an important role in the global geochemical nitrogen cycle. They are globally distributed in diverse environments and contribute to the loss of reactive nitrogen species in agricultural soils. However, little is known about the key metabolic enzymes responsible for their main energy metabolism, the conversion of ...
