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 ...

Ammonia-oxidizing bacteria and archaea exhibit differential nitrogen source preferences
Nature MicrobiologyAmmonia-oxidizing microorganisms (AOM) contribute to one of the largest nitrogen fluxes in the global nitrogen budget. Four distinct lineages of AOM: ammonia-oxidizing archaea (AOA), beta- and gamma-proteobacterial ammonia-oxidizing bacteria (β-AOB and γ-AOB) and complete ammonia oxidizers (comammox), are thought to compete for ammonia as their primary

Ammonia-Oxidizing Archaea in Marine Cold-Water Sponges
2011Thaumarchaea (Archaea) kommen in vielen terrestrischen und marinen Lebensräumen vor und sind oftmals mit marinen Schwämmen assoziiert. Basierend auf Metagenom- und Kultivierungsstudien hat sich gezeigt, dass viele (wenn nicht sogar alle) Thaumarchaea die Fähigkeit besitzen, mittels dem Enzym Ammoniummonooxygenase (AMO), Ammonium zu oxidieren. In dieser

Characterization of ammonia-oxidizing archaea by Raman microspectroscopy
2012Nitrifikation 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 ...

Ecology of ammonia-oxidizing archaea under oxygen depletion
Ammoniak-oxiderende archaea (AOA) er ubikvitære mikroorganismer, der er afhængige af ammoniak (NH₃) oxidation til nitrit (NO₂⁻) for at udvinde energi. På trods af deres afhængighed af ilt kan de findes i iltfattige marine miljøer. Nyere opdagelser har antydet, at deres tilstedeværelse i iltfattige miljøer kan forklares ved iltproduktion gennem NO ...openaire +2 more sources
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 ...openaire +1 more source
