Monoclonal 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 کاملKinetics 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 کاملComplete genome sequence of Nitrobacter hamburgensis X14 and comparative genomic analysis of species within the genus Nitrobacter.
The alphaproteobacterium Nitrobacter hamburgensis X14 is a gram-negative facultative chemolithoautotroph that conserves energy from the oxidation of nitrite to nitrate. Sequencing and analysis of the Nitrobacter hamburgensis X14 genome revealed four replicons comprised of one chromosome (4.4 Mbp) and three plasmids (294, 188, and 121 kbp). Over 20% of the genome is composed of pseudogenes and p...
متن کاملNitrobacter winogradskyi transcriptomic response to low and high ammonium concentrations.
Nitrobacter winogradskyi Nb-255 is a nitrite-oxidizing bacterium that can grow solely on nitrite (NO2(-)) as a source of energy and nitrogen. In most natural situations, NO2(-) oxidation is coupled closely to ammonium (NH4(+)) oxidation by bacteria and archaea and, conceptually, N. winogradskyi can save energy using NH4(+) to meet its N-biosynthetic requirements. Interestingly, NH4(+) delayed t...
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...
