A bioluminescence assay using Nitrosomonas europaea for rapid and sensitive detection of nitrification inhibitors.
An expression vector for the luxAB genes, derived from Vibrio harveyi, was introduced into Nitrosomonas europaea. Although the recombinant strain produced bioluminescence due to the expression of the luxAB genes under normal growing conditions, the intensity of the light emission decreased immediately, in a time-and dose-dependent manner, with the addition of ammonia monooxygenase inhibitors, s...
متن کاملNitrosomonas europaea expresses a nitric oxide reductase during nitrification.
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 and membrane protein fractions, which was restored by the introduction of an intact norCBQD gene cluster in trans. NorB-deficient cells produced ...
متن کاملEnzyme Immunoassay Detection of Nitrosomonas europaea.
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, including plating, activity, and fluorescence immunoassay techniques. Following an i...
متن کاملDevelopment of a Nano-ELISA system for the rapid and sensitive detection of H9N2 avian influenza
Influenza is one of the most important viral diseases that is common among the birds and the mammalsand is caused by specific viruses that belong to the Orthomyxoviridae family. Migratory aquatic birds arethe reservoir of the disease and there is a likelihood of the disease in any region. There are differentmethods for detecting the avian influenza, but by the point of detection rates, the ELIS...
متن کاملCandidate stress genes of Nitrosomonas europaea for monitoring inhibition of nitrification by heavy metals.
Heavy metals have been shown to be strong inhibitors of nitrification in wastewater treatment plants. In this research, the effects of cadmium, copper, and mercury on Nitrosomonas europaea were studied in quasi-steady-state batch reactors. When cells were exposed to 1 microM CdCl2, 6 microM HgCl2, or 8 microM CuCl2, ammonia oxidation rates were decreased by about 90%. Whole-genome transcription...
