Molekulare und physiologische Charakterisierung des Energiestoffwechsels von Nitrosomonas europaea
Die lösliche Ammoniak-Monooxygenase (AMO) aus Nitrosomonas europaea ist in ungefähr der gleichen Menge wie die membrangebundene AMO vorhanden. Beide Formen sind in vivo aktiv und besitzen eine ähnliche spezifische Aktivität. Die lösliche AMO ist ein Cu-, Fe- und möglicherweise auch Zn-haltiges …

Variations in the Oxidative Rates of Nitrosomonas europaea in Coke-Plant Activated Sludge.
… contains about four orders of magnitude more Nitrosomonas cells than found by most probable number estimates. Nitrosomonas was found to comprise about 2 percent of the total cells in coke-plant mixed liquor maintained at a 25-day solids retention time (SRT) or greater, and about 1 percent at …

Characterizing biological nitrification inhibition using native Nitrosomonas europaea: mechanism studies and maize cultivar screening
… ammonia-oxidizing bacteria (AOB), such as Nitrosomonas europaea, oxidize NH₄⁺ and ammonia (NH₃) to nitrite (NO₂⁻), which is further converted to nitrate (NO₃⁻) by nitrite-oxidizing microorganisms and eventually reduced to di-nitrogen (N₂) via denitrification. These processes release nitrous …

Biochemical Characterization of Self-Sacrificing P-Aminobenzoate Synthases from Chlamydia Trachomatis and Nitrosomonas Europaea
… some organisms such as Chlamydia trachomatis and Nitrosomonas europaea which do not contain the canonical THF biosynthesis genes, despite still being able to synthesize THF de novo. Previous studies have shown that these organisms do not contain the pabABC genes, normally required to synthesize …

The effect of simazine on nitrification and the decomposition of simazine by soil microorganisms
… The herbicide had no effect on the growth of Nitrosomonas europaea in shake flask culture, but did inhibit the growth of Nitrobacter agilis. The addition of yeast extract to the culture medium did not reverse the inhibition. Simazine did not inhibit the respiration of N. agilis even at a …

Micropollutants biotransformation by two nitrifying communities enriched from biofilm of a nitrification trickling tower
… However, when using pure AOB cultures, such as Nitrosomonas europaea, only few of these micropollutants could be biotransformed. Such discrepancy might due to the facts that the tested pure cultures were disparate with the AOB in NAS, and the microorganisms dependently growing with AOB, such as …

Ammonia-monooxygenase-mediated cometabolic biotransformation and abiotic transformation of micropollutants
… NOB pure culture (Nitrobacter sp.), and an AOB (Nitrosomonas europaea)/NOB co-culture for fifteen MPs, whose biotransformation were associated with nitrification activities. The NOB did not biotransform any MP investigated, whereas the AOB/NOB co-culture was capable of biotransforming asulam, and …

Biochemistry: Production of recombinant Rh blood group antigens for detection of alloimmunisation
… to construct a hybrid Rh protein comprised of a Nitrosomonas europaea (N. europaea) Rh50 backbone containing di erent external loops of the human RhD protein. Human RhD external loop 6 was the most suitable candidate to start with due to its location between highly conserved domains of the …

Viabilidad de un proceso para la eliminación conjunta de H2S y NH3 contenido en efluentes gaseosos
… de H2S (BTT) y el otro biofiltro percolador con Nitrosomonas europaea ATCC 19718 para la eliminación de NH3 (BNE). El efecto del la velocidad superficial del medio de recirculación, concentraciones de nitrito y sulfato, pH, tiempo de residencia en el lecho (EBRT) y cargas de entrada de NH3 y H2S …

Chemical Inhibition of Nitrification: Evaluating Methods to Detect and Characterize Inhibition and the Role of Selected Stress Responses Upon Exposure to Oxidative and Hydrophobic Toxins
… does not exist in two nitrifying bacteria, Nitrosomonas europaea and Nitrospira moscoviensis. Furthermore, we showed that another important antioxidant molecule, glutathione, was not oxidized as readily as in a non-nitrifying bacterium. Furthermore, we hypothesized that hydrophobic …

Assessing the Impacts of Silver Nanoparticles on the Growth, Diversity, and Function of Wastewater Bacteria
… AgNPs on the ammonia oxidizing bacterium (AOB) Nitrosomonas europaea and investigate possible mechanisms for toxicity, 2) test the effects of consumer product AgNPs on a wide range of heterotrophic bacteria, 3) evaluate the effects of AgNPs on bench scale wastewater sequencing batch reactors, …

The Effect of Chlorine and Chloramines on the Viability and Activity of Nitrifying Bacteria
… of E. coli and the ammonia-oxidizing bacterium Nitrosomonas europaea, and found that many of the known stress response mechanisms and genes present in E. coli are absent in N. europaea or not controlled by the same mechanisms specific to bacterial growth state. These genetic differences present …

Elucidating Factors that Impact the Removal of Organic Microconstituents by Ammonia Oxidizing and Heterotrophic Bacteria
Although wastewater treatment plants are a line of defense in minimizing indiscriminate output of microconstituents to natural waters, we do not possess a fundamental understanding of the mechanisms involved in microconstituent removal during wastewater treatment. With this in mind, experiments …
