Kinetics of nitrite oxidation by Nitrobacter winogradskyi.
Preliminary data on the kinetics of the oxidation of nitrite by Nitrobacter were presented by Laudelout & van Tichelen (1960). The present observations complete and extend the results concerning the effects of pH, concentrations of nitrite and of nitrate, temperature and oxygen partial pressure on the parameters of the rate equation for the oxidation of nitrite by intact cells and cell-free ext...
متن کاملKinetics of the nitrite oxidation by Nitrobacter winogradskyi.
Few quantitative studies of the biological oxidation of nitrite by Nitrobacter have been made, although this process is important in nature. Without it, the concentration of nitrite produced by the oxidation of ammonia would soon reach toxic levels in water or in the soil. The influence of temperature and substrate concentration on the rate of this reaction has never been quantitatively studied...
متن کاملAmmonia stimulates growth and nitrite-oxidizing activity of Nitrobacter winogradskyi
The aim of this study was to obtain a nitrite-oxidizing bacterium with high nitrite oxidation activity for controlling nitrite levels. A nitrite-oxidizing bacterium, ZS-1, was isolated from the water of a coastal Pseudosciaena crocea-rearing pond. The strain was identified as Nitrobacter winogradskyi based on the phylogenetic analyses of the 16S ribosomal ribonucleic acid gene and nxrA sequence...
متن کاملMonoclonal antibodies recognizing nitrite oxidoreductase of Nitrobacter hamburgensis, N. winogradskyi, and N. vulgaris.
Three monoclonal antibodies (MAbs) against nitrite oxidoreductase (NOR) of Nitrobacter hamburgensis were produced. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting analysis of the purified enzyme showed that the MAbs named Hyb 153.1 and Hyb 153.3 both recognized a protein with a molecular mass of 64,000 Da, while Hyb 153.2 recognized a protein with a molecular mass o...
متن کاملGenome sequence of the chemolithoautotrophic nitrite-oxidizing bacterium Nitrobacter winogradskyi Nb-255.
The alphaproteobacterium Nitrobacter winogradskyi (ATCC 25391) is a gram-negative facultative chemolithoautotroph capable of extracting energy from the oxidation of nitrite to nitrate. Sequencing and analysis of its genome revealed a single circular chromosome of 3,402,093 bp encoding 3,143 predicted proteins. There were extensive similarities to genes in two alphaproteobacteria, Bradyrhizobium...
