Nitrobacter 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 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 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 کاملA New Acyl-homoserine Lactone Molecule Generated by Nitrobacter winogradskyi.
It is crucial to reveal the regulatory mechanism of nitrification to understand nitrogen conversion in agricultural systems and wastewater treatment. In this study, the nwiI gene of Nitrobacter winogradskyi was confirmed to be a homoserine lactone synthase by heterologous expression in Escherichia coli that synthesized several acyl-homoserine lactone signals with 7 to 11 carbon acyl groups. A n...
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...
