Iron requirement for the hydrogenase of Desulfovibrio desulfuricans
Archives of Biochemistry and Biophysics, 1964Abstract Aged preparations of the hydrogenase of D. desulfuricans develop a requirement of ferrous iron for activity. This supports the view that ferrous iron is a part of the active enzyme. It is suggested that inactivation during storage of the enzyme results from the loss of ferrous iron by the enzyme and oxidation of the iron to the ferric ...

Desulfovibrio desulfuricans growth kinetics
Environmental Toxicology and Water Quality, 1991AbstractGrowth kinetics of Desulfovibrio desulfuricans, strain NCIMB 9467, was studied in laboratory scale, under well‐controlled batch conditions. This research is oriented toward the practical, industrial removal of sulfate and metal ions from mine water.

Desulfovibrio desulfuricans bacteremia: A case report and literature review
Anaerobe, 2018Desulfovibrio spp. are sulfate-reducing, anaerobic bacteria that are ubiquitously found in the environment. These organisms infrequently cause human infections, and the clinical characteristics of infection with Desulfovibrio spp. remain unclear. Here, we describe a case of Desulfovibrio desulfuricans bacteremia in an 88-year-old Japanese man with a ...

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.

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 ...

Toxic effects of uranium on Desulfovibrio desulfuricans G20
Environmental Toxicology and Chemistry, 2006Abstract The toxic effects of U(VI) were studied using Desulfovibrio desulfuricans G20 in a medium containing bicarbonate or 1,4-piperazinediethane sulfonic acid disodium salt monohydrate (PIPES) buffer (each at 30 mM and pH 7). Uranium(VI) toxicity was dependent on the medium buffer and was observed in terms of longer lag times and, in ...

Anaerobic oxidation of hydrocarbons by Desulfovibrio desulfuricans
Chemical Geology, 1966Abstract Data are presented which indicate a slow oxidation of radioactive methane, ethane and n -octadecane by Desulfovibrio desulfuricans isolated from a fresh water oil-bearing aquifer, the Carrizo (Eocene) Formation. Oxidation of n -octadecane by sulfate-reducer bacterial cells was indicated also by methylene blue reduction in controlled ...

Enzymatic catalysis of mercury methylation by Desulfovibrio desulfuricans LS
Applied and Environmental Microbiology, 1994The recently defined role of methylcobalamin in Hg2+ methylation by Desulfovibrio desulfuricans LS enabled us to reexamine the question of whether the principal source of methylmercury is spontaneous transmethylation or an enzymatically catalyzed process. In cell extracts of D.

Comparative studies of two ferredoxins from Desulfovibrio desulfuricans Norway
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1980Two ferredoxins isolated from Desulfovibrio desulfuricans Norway have been purified and characterized. The less acidic, designated as ferredoxin I, contains four iron atoms, four acid-labile sulfur groups and six cysteine residues per molecule. Ferredoxin II is more acidic and abundant than ferredoxin I, but is very unstable to O2.

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1979
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.
