Phanerozoic radiation of ammonia oxidizing bacteria [PDF]
Scientific Reports, 2021 The modern nitrogen cycle consists of a web of microbially mediated redox transformations. Among the most crucial reactions in this cycle is the oxidation of ammonia to nitrite, an obligately aerobic process performed by a limited number of lineages of ...

Biogeography of anaerobic ammonia-oxidizing (anammox) bacteria [PDF]
Frontiers in Microbiology, 2014 Anaerobic ammonia-oxidizing (anammox) bacteria are able to oxidize ammonia and reduce nitrite to produce N2 gas. After being discovered in a wastewater treatment plant (WWTP), anammox bacteria were subsequently characterized in natural environments ...

Dating Ammonia-Oxidizing Bacteria with Abundant Eukaryotic Fossils. [PDF]
Mol Biol EvolAbstractEvolution of a complete nitrogen cycle relies on the onset of ammonia oxidation, which aerobically converts ammonia to nitrogen oxides. However, accurate estimation of the antiquity of ammonia-oxidizing bacteria (AOB) remains challenging because AOB-specific fossils are absent and bacterial fossils amenable to calibrate bacterial molecular ...

Selective Enrichment of Nitrososphaera viennensis-Like Ammonia-Oxidizing Archaea over Ammonia-Oxidizing Bacteria from Drinking Water Biofilms [PDF]
Microbiology Spectrum, 2022 Ammonia-oxidizing archaea (AOA) can oxidize ammonia to nitrite for energy gain. They have been detected in chloraminated drinking water distribution systems (DWDS) along with the more common ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria

Ammonia oxidizers offset acidification stress via adaptive substrate affinity in aquatic ecosystems [PDF]
Nature CommunicationsAmmonia oxidation, a critical nitrogen cycle process, exhibits contradictory responses to aquatic acidification, and the underlying mechanism remains unresolved. Here, through pH manipulation experiments across diverse ecosystems and with a model ammonia-

Characterization of a long overlooked copper protein from methane- and ammonia-oxidizing bacteria [PDF]
Nature Communications, 2018 Methane- and ammonia-oxidizing bacteria use the integral membrane, copper-dependent enzymes particulate methane monooxygenase (pMMO) and ammonia monooxygenase (AMO) to oxidize methane and ammonia.

Ammonia-Oxidizing Archaea (AOA) Play with Ammonia-Oxidizing Bacteria (AOB) in Nitrogen Removal from Wastewater. [PDF]
Archaea, 2018 An increase in the number of publications in recent years indicates that besides ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) may play an important role in nitrogen removal from wastewater, gaining wide attention in the wastewater engineering field.

Shifts of ammonia-oxidation process along salinity gradient in an estuarine wetland
Ecological Indicators, 2022 Ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) play an important role in nitrogen (N) cycling of the estuarine sediments. However, the shifts of potential ammonia oxidation rates (PARs) of AOA and AOB along different salinity ...

Similar Microbial Communities Found on Two Distant Seafloor Basalts. [PDF]
, 2015 The oceanic crust forms two thirds of the Earth's surface and hosts a large phylogenetic and functional diversity of microorganisms. While advances have been made in the sedimentary realm, our understanding of the igneous rock portion as a microbial ...
