Biological inhibition of soil nitrification by forest tree species affects Nitrobacter populations.

Environmental Microbiology, 2019
Some temperate tree species are associated with very low soil nitrification rates, with important implications for forest N dynamics, presumably due to their potential for biological nitrification inhibition (BNI).

Shifts in Nitrobacter- and Nitrospira-like nitrite-oxidizing bacterial communities under long-term fertilization practices

Soil Biology and Biochemistry, 2018
Nitrite-oxidizing bacteria (NOB) are key players in the second step of nitrification, which is an important process in the soil nitrogen (N) cycle.

Photoinaktivierung von Nitrobacter winogradskyi Buch

Archiv f�r Mikrobiologie, 1961
1. Licht hemmt die Oxydationstatigkeit von Nitrobacter winogradskyi bis zur volligen Oxydationsruhe. 2. Die Inaktivierung ist um so starker, je langer das Licht einwirkt und je starker die Lichtintensitat ist. 3. Nach totaler Photoinaktivierung setzt im Dunkeln eine Erholung ein. 4. Die Reaktivierung beginnt um so

An amperometric enzyme-linked immunosensor for Nitrobacter

Applied Microbiology and Biotechnology, 1998
A new amperometric enzyme-linked immunoassay for specific enumeration of Nitrobacter has been developed. This assay uses an electrode made of glassy carbon, on which the immunological reaction is carried out. The method is based on a competitive immunoassay principle, utilising monoclonal primary antibody and alkaline-phosphatase-labelled secondary ...

Characterization of cytochrome c from Nitrobacter Agilis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1969
Abstract Cytochrome c from Nitrobacter agilis was isolated and purified approx. 60-fold. Absorption spectra of both the oxidized and the reduced Nitrobacter cytochrome c and the oxidized minus reduced difference spectrum of this cytochrome were essentially identical to the corresponding spectra of horse-heart cytochrome c .

Optimization of the medium for the growth of Nitrobacter winogradskyi by statistical method

Letters in Applied Microbiology, 2018
Although Nitrobacter winogradskyi is an important chemoorganotrophic organism for the study of nitrite‐oxidizing bacteria physiology as well as nitrification, until now, the mixotrophic medium for this organism growth has not been optimized ...

The mechanism of nitrite oxidation by Nitrobacter winogradskyi

Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966
Summary 1. With exception of certain narcotics, the effect of classical inhibitors on the nitrite respiration of Nitrobacter winogradskyi was in agreement with the usual inhibition pattern characteristic of a cytochrome respiratory chain. Strong inhibition by quinacrine and its reversal by flavin-adenine dinucleotide shows that a flavin is ...

Characterization of Nitrobacter agilis immobilized in calcium alginate

Enzyme and Microbial Technology, 1986
Nitrobacter agilis cells have been immobilized in calcium alginate and the resulting preparation was used as a biocatalyst for the oxidation of nitrite to nitrate ions. The influence of pH, temperature, and the size and cell load of the biocatalyst beads on the activity was determined, as well as the storage and operational stability of the system. The
