Transcriptomic Response of Nitrosomonas europaea Transitioned from Ammonia- to Oxygen-Limited Steady-State Growth [PDF]
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]
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]
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]
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.

A Potentiometric Flow Biosensor Based on Ammonia-Oxidizing Bacteria for the Detection of Toxicity in Water [PDF]
A flow biosensor for the detection of toxicity in water using the ammonia-oxidizing bacterium (AOB) Nitrosomonas europaea as a bioreceptor and a polymeric membrane ammonium-selective electrode as a transducer is described.

Genome-Scale, Constraint-Based Modeling of Nitrogen Oxide Fluxes during Coculture of
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]
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 ...

Inhibition of Targeted Bacterial Growth Using MazF-Expressing Phagemids: A Novel Therapeutic Approach Based on Endoribonuclease Toxin Molecules. [PDF]
ABSTRACT The extensive and indiscriminate use of antibiotics, which are intended to halt bacterial growth or eliminate them, has unintentionally given rise to antimicrobial resistance (AMR), which is a critical threat to global health. In the pursuit of alternative solutions, researchers have focused on type II toxin–antitoxin systems prevalent within ...
