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 کاملNitrite oxidase and nitrate reductase in Nitrobacter agilis.
Nitrite oxidase and nitrate reductase in Nitrobacter agilis were shown to be separate enzymes. The best separation of the two systems was achieved by ammonium sulphate fractionation. The effects of various compounds, including antimycin A, 2-n-heptyl-4-hydroxyquinoline N-oxide and chlorate, also clearly distinguish between the two enzyme reactions. The relationship between the two opposing reac...
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 کاملPermeability of Nitrobacter agilis to Organic Compounds.
Ida, S. (Cornell University, Ithaca, N.Y.), and M. Alexander. Permeability of Nitrobacter agilis to organic compounds. J. Bacteriol. 90:151-156. 1965.-None of a variety of inorganic ions or organic compounds served as a sole energy source for the growth of Nitrobacter agilis, and the test substrates were not oxidized by either intact cells or extracts of the obligate chemoautotroph. The organic...
متن کاملCharacterization of a Nitrate Reductase from the Chemoautotroph Nitrobacter agiZis*
The energy thus liberated is used in part for the assimilation of carbon dioxide which serves as the sole carbon source for growth. Studies of the biochemistry of Nitrobacter agilis have been mainly limited by the difficulty in obtaining large yields of cells, as has been the case with many of the chemoautotrophs. There has consequently been a relat.ively slow advancement of biochemical researc...
