Transcriptomic Response of Nitrosomonas europaea Transitioned from Ammonia- to Oxygen-Limited Steady-State Growth. [PDF]
MSystems, 2020 Ammonia-oxidizing microorganisms perform the first step of nitrification, the oxidation of ammonia to nitrite. The bacterium Nitrosomonas europaea is the best-characterized ammonia oxidizer to date. Exposure to hypoxic conditions has a profound effect on

RNA extraction protocol from low-biomass bacterial Nitrosomonas europaea and Nitrobacter winogradskyi cultures for whole transcriptome studies [PDF]
STAR Protocols, 2023 Summary: RNA-sequencing for whole transcriptome analysis requires high-quality RNA in adequate amounts, which can be difficult to generate with low-biomass-producing bacteria where sample volume is limited.

Nitrosomonas europaea MazF Specifically Recognises the UGG Motif and Promotes Selective RNA Degradation [PDF]
Frontiers in Microbiology, 2018 Toxin-antitoxin (TA) systems are implicated in prokaryotic stress adaptation. Previously, bioinformatics analysis predicted that such systems are abundant in some slowly growing chemolithotrophs; e.g., Nitrosomonas europaea.

AAU-Specific RNA Cleavage Mediated by MazF Toxin Endoribonuclease Conserved in Nitrosomonas europaea [PDF]
Toxins, 2016 Nitrosomonas europaea carries numerous toxin-antitoxin systems. However, despite the abundant representation in its chromosome, studies have not surveyed the underlying molecular functions in detail, and their biological roles remain enigmatic.

Genome-Scale, Constraint-Based Modeling of Nitrogen Oxide Fluxes during Coculture of
mSystems, 2018 Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, emits nitrogen (N) oxide gases (NO, NO2, and N2O), which are potentially hazardous compounds that contribute to global warming.

Effect of Low-Density Static Magnetic Field on the Oxidation of Ammonium by Nitrosomonas europaea and by Activated Sludge in Municipal Wastewater [PDF]
Food Technology and Biotechnology, 2015 Ammonium removal is a key step in biological wastewater treatment and novel approaches that improve this process are in great demand. The aim of this study is to test the hypothesis that ammonium removal from wastewater can be stimulated by static ...

Linking Abundance and Activity of Ammonia-Oxidising Bacteria and Archaea in an Agriculturally Impacted First-Order Stream. [PDF]
Environ MicrobiolAmmonia‐oxidising archaea (AOA) and bacteria (AOB) coexist in streambed sediments, but their contributions to nitrification remain unresolved. Using field sampling, sequencing, qPCR, microcosm incubations and modelling, we show that AOB dominated nitrification in streambed sediments despite lower abundance, emphasizing the importance of distinguishing ...

Application of an integrated statistical design for optimization of culture condition for ammonium removal by Nitrosomonas europaea. [PDF]
PLoS ONE, 2013 Statistical methodology was applied to the optimization of the ammonium oxidation by Nitrosomonas europaea for biomass concentration (C(B)), nitrite yield (Y(N)) and ammonium removal (R(A)).
