Structure of the Nitrosomonas europaea Rh protein. [PDF]
Proc Natl Acad Sci U S A, 2007 Amt/MEP/Rh proteins are a family of integral membrane proteins implicated in the transport of NH 3 , CH 2 NH 2 , and CO 2 . Whereas Amt/MEP proteins are agreed to transport ammonia (NH 3 /NH 4 +

Reactivation of Microbial Strains and Synthetic Communities After a Spaceflight to the International Space Station: Corroborating the Feasibility of Essential Conversions in the MELiSSA Loop [PDF]
, 2019 To sustain human deep space exploration or extra-terrestrial settlements where no resupply from the Earth or other planets is possible, technologies for in situ food production, water, air, and waste recovery need to be developed.

Cytochrome aa3 from Nitrosomonas europaea.
Journal of Biological Chemistry, 1986 Cytochrome c oxidase has been purified from the ammonia oxidizing chemoautotroph Nitrosomonas europaea by ion-exchange chromatography in the presence of Triton X-100. The enzyme has absorption maxima at 420 and 592 nm in the resting state and at 444 and 598 nm in the dithionite-reduced form; optical extinction coefficient (598 nm minus 640 nm) = 21.9 ...

Zhejiang Daxue xuebao. Lixue ban, 2004 为了分析污水处理系统中氨氧化细菌的种群组成，筛选合成了 一对对氨氧化细菌氨单加氧酶基因(amoA) 特异结合的引物序列，利用PCR技术对从活性污泥中抽提的细菌总DNA进行扩增，得到不同重组子的amoA序列片段.运用BLAST程序将测序结果与基因库中的公开序列进行比较，发现在该污水处理系统中分布有大量亚硝化单胞菌属(Nitrosomonas)细菌，其中最主要的是欧洲亚硝化单胞菌(Nitrosomonas europaea)，由此推测Nitrosomonas属细菌在该系统的氨氧化过程中起主导作用.

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]
, 2010 Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.

Anoxic nitrification in marine sediments [PDF]
, 2004 Nitrate peaks are found in pore-water profiles in marine sediments at depths considerably below the conventional zone of oxic nitrification. These have been interpreted to represent nonsteady- state effects produced by the activity of nitrifying ...

Nitrosomonas europaea expresses a nitric oxide reductase during nitrification. [PDF]
, 2004 In this paper, we report the identification of a norCBQD gene cluster that encodes a functional nitric oxide reductase (Nor) in Nitrosomonas europaea. Disruption of the norB gene resulted in a strongly diminished nitric oxide (NO) consumption by cells ...
