Periplasmic oxygen reduction by Desulfovibrio species
Archives of Microbiology, 2001Washed cells of Desulfovibrio vulgaris strain Marburg (DSM 2119) reduced oxygen to water with H(2) as electron donor at a mean rate of 253 nmol O(2) min(-1) (mg protein)(-1). After separating the periplasm from the cells, more than 60% of the cytochrome c activity and 90% of the oxygen-reducing activity were found in the periplasmic fraction.

Summary Cyclic voltammetry has shown that reduction-reoxidation processesof D. vulgaris Hildenborough and D. desulfuricans Norway cytochromes c 3 correspond to rather fast electronic exchanges. Two steps for the former and three (two of which are very close) for the latter are detected.

Purification and properties of the hydrogenase of Desulfovibrio desulfuricans
Biochimica et Biophysica Acta, 1956Abstract Hydrogenase from Desulfovibrio desulfuricans has been purified about fifty-fold. At the highest level of purity 1 mg of protein N catalyses the oxidation of 2.6·10 6 μl of H 2 per hour by methylene blue at 34°. Purified hydrogenase was found to be activated by FeCl 2 or FeCl 3 , the increase in activity being the same with benzyl ...

A strain of desulfovibrio able to use oxamate
Archiv f�r Mikrobiologie, 1963Strain Monticello 2, a variant of Desulfovibrio desulfuricans, was isolated from an environment associated with Streptococcus allantoicus, which converts allantoin to oxamate. The strain grew with oxamate or oxalate, as well with more conventional substrates for Des. desulfuricans; yeast extract was essential for growth with oxamate, but not for growth

Hydrogenase Genes in Desulfovibrio
1990The objective of this mini-review is to discuss the different types of hydrogenases that are found in sulfate-reducing bacteria from a molecular biological perspective. Since molecular biology may mean different things to different people, it will be defined for the purpose of this mini-review as the field of science dealing with the (1) cloning, (2 ...

Characterization of sulfate transport in Desulfovibrio desulfuricans
Archives of Microbiology, 1989Uptake of 35S-labelled sulfate was studied with a new isolate of Desulfovibrio desulfuricans, strain CSN. Micromolar additions of sulfate (1-10 microM or nmol/mg protein) to cell suspensions incubated in 150 mM KCl at -1 degrees C were almost completely taken up and accumulated about 5,000-fold.

Disulfur Monoxide: Production by Desulfovibrio
Science, 1967Desulfovibrio desulfuricans growing on agar surfaces produces a gas that appears to be identical to "Schenk's sulfur monoxide," which was later identified as disulfur monoxide. The gas stimulates surface growth of Desulfovibrio on an agar medium and is used by the cells as an electron donor for the ...
