Hydrogenase mediated nitrite reduction in chlorella.
The assay of the hydrogenase of glucose-grown cells of Chlorella pyrenoidosa, strain 7-11-05 by means of nitrite reduction with molecular hydrogen is described. The hydrogenase of Chlorella shows maximum activity immediately after equilibration in the hydrogen atmosphere. The hydrogenase mediated reduction of nitrite to ammonia requires the presence of CO(2). However, at pH 6.4. when the reacti...
متن کاملNitrate Reduction and Assimilation in Chlorella
1. Nitrate reduction and assimilation have been studied in Chlorella pyrenoidosa under growth conditions by observing effects on the CO(2)/O(2) gas exchange quotient. 2. During assimilation of glucose in the dark, nitrate reduction is noted as an increase in the R.Q. to about 1.6 caused by an increased rate of carbon dioxide production. 3. During photosynthesis at low light intensity nitrate re...
متن کاملNitrate and Nitrite Reduction in Relation
Soybean (Gcine nax L. cv Williams) seeds were sown in pots containing a 1:1 perlite-vermiculite mixture and grown under greenhouse coditions. Nodules were initiated with a nitrate reductase expressing strain of Rhizobiumjaponicwn, USDA 110, or with nitrate reductase nonexpressing mutants (NR108, NR303) derived from USDA 110. Nodules initiated with either type of strain were normal in appearance...
متن کاملNitrite reduction by copper complexes.
A series of copper complexes have been synthesised as potential agents for the catalytic reduction of nitrite anions. The ligands and corresponding copper complexes have been characterised by using a range of techniques including X-ray crystallography, NMR, microanalysis, mass spectrometry, infra-red spectroscopy, electrochemical studies and density functional theory calculations. For complexes...
متن کاملReduction of technetium(VII) by Desulfovibrio fructosovorans is mediated by the nickel-iron hydrogenase.
Resting cells of the sulfate-reducing bacterium Desulfovibrio fructosovorans grown in the absence of sulfate had a very high Tc(VII)-reducing activity, which led to the formation of an insoluble black precipitate. The involvement of a periplasmic hydrogenase in Tc(VII) reduction was indicated (i) by the requirement for hydrogen as an electron donor, (ii) by the tolerance of this activity to oxy...
