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.

Reduction and Immobilization of Molybdenum by Desulfovibrio desulfuricans
Journal of Environmental Quality, 1997AbstractThe mobility of Mo in the environment is strongly dependent on its chemical oxidation state. Under oxidizing conditions, Mo occurs as highly soluble and mobile Mo(VI) and Mo(V) compounds. However, under reducing conditions Mo usually forms insoluble Mo(IV) phases.

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 ...

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 ...

No cofactor effect on equilibrium unfolding of Desulfovibrio desulfuricans flavodoxin
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 2000Flavodoxins are proteins with an alpha/beta doubly wound topology that mediate electron transfer through a non-covalently bound flavin mononucleotide (FMN). The FMN moiety binds strongly to folded flavodoxin (K(D)=0.1 nM, oxidized FMN). To study the effect of this organic cofactor on the conformational stability, we have characterized apo and holo ...

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 ...

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.

Factors affecting the production of hydrogenase by Desulfovibrio desulfuricans
Canadian Journal of Microbiology, 1980An examination of conditions for the growth of Desulfovibrio desulfuricans, with the aim of optimizing hydrogenase production, is reported. An ammonium sulfate – lactate – yeast extract medium gave 5 to 10 times as much hydrogenase activity as a peptone – yeast extract medium.

Immunological and enzymatic properties of the Desulfovibrio desulfuricans hydrogenase
Canadian Journal of Microbiology, 1984Affinity-purified antibodies specific for the purified, active periplasmic hydrogenase of Desulfovibrio desulfuricans were prepared. Immunodiffusion and enzyme-linked immunosorbent assay (ELISA) methods showed distinct differences between the native form of hydrogenase and the enzyme modified by heat, acid, active-site, and group-specific chemical ...

Cloning and characterization of the flavodoxin gene from Desulfovibrio desulfuricans
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1991The gene coding for the flavodoxin protein from Desulfovibrio desulfuricans [Essex 6] (ATCC 29577) has been cloned and sequenced. The gene was identified on Southern blots of HindIII-digested genomic DNA by hybridization to the coding region for the flavodoxin from Desulfovibrio vulgaris [Hildenborough] (Krey, G.D., Vanin, E.F. and Swenson, R.P. (1988)
