Proton electrochemical gradients in washed cells of Nitrosomonas europaea and Nitrobacter agilis.
The components of the proton motive force (Deltap), namely, membrane potential (Deltapsi) and transmembrane pH gradient (DeltapH), were determined in the nitrifying bacteria Nitrosomonas europaea and Nitrobacter agilis. In these bacteria both Deltapsi and DeltapH were dependent on external pH. Thus at pH 8.0, Nitrosomonas europaea and Nitrobacter agilis had Deltapsi values of 173 mV and 125 mV ...
متن کاملLack of distinction between Nitrobacter agilis and Nitrobacter winografskyi.
No adequate criteria were established to distinguish between Nitrobacter agilis and N. winogradskyi. However, very gentle preparative techniques permitted demonstration of flagella in N. agilis.
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 کاملMethane oxidation by Nitrosomonas europaea.
Methane inhibited NH4+ utilization by Nitrosomonas europaea with a Ki of 2mM. O2 consumption was not inhibited. In the absence of NH4+, or with hydrazine as reductant, methane caused nearly a doubling in the rate of O2 uptake. The stimulation was abolished by allylthiourea, a sensitive inhibitor of the oxidation of NH4+. Analysis revealed that methanol was being formed in these experiments, wit...
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...
