Inhibition of bacterial ammonia oxidation by organohydrazines in soil microcosms
Hydroxylamine oxidation by hydroxylamine oxidoreductase (HAO) is a key step for energy-yielding in support of the growth of ammonia-oxidizing bacteria (AOB).

Optimization of RNA extraction for bacterial whole transcriptome studies of low-biomass samples
Summary: We developed a procedure for extracting maximal amounts of high-quality RNA from low-biomass producing (autotrophic) bacteria for experiments where sample volume is limited.

Enzyme Immunoassay Detection of Nitrosomonas europaea [PDF]
An exploratory effort to selectively detect the presence of a nitrifying bacterium, Nitrosomonas europaea , successfully demonstrated the fundamental utility of an enzyme-based immunoassay protocol. The applied polyclonal antibody test seemingly offered a marked improvement over the available analytical options ...

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.

Iron acquisition and its regulation in Nitrosomonas europaea [PDF]
Iron is absolutely necessary for the maintenance, the defense, the differentiation and last, but by no means least, the growth and cellular division of almost all living organisms including Nitrosomonas europaea, an ammonia oxidizing bacterium. Given the

Transformations of Aromatic Compounds by Nitrosomonas europaea [PDF]
Benzene and a variety of substituted benzenes inhibited ammonia oxidation by intact cells of Nitrosomonas europaea. In most cases, the inhibition was accompanied by transformation of the aromatic compound to a more oxidized product or products.

Aerobic metabolism of mixed culture of ammonia oxidation
Denitrification with ammonia as electron donor is a new microbial reaction, named anaerobic ammonia oxidation. The characteristics of mixed culture from an anaerobic ammonia oxidation reactor are compared with those of Nitrosomonas europaea and those of ...

Characterization of the ferrioxamine uptake system of Nitrosomonas europaea [PDF]
The chemolithoautotroph Nitrosomonas europaea has two genes predicted to encode outer-membrane (OM) ferrioxamine transporters. Expression of the ferrioxamine uptake system required induction, as shown by the shorter lag phase in ferrioxamine-containing cultures when ferrioxamine-exposed cells were used as an inoculum.
