The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]
, 2014 Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of

Intracellular Hg(0) Oxidation in Desulfovibrio desulfuricans ND132 [PDF]
, 2016 The disposal of elemental mercury (Hg(0)) wastes in mining and manufacturing areas has caused serious soil and groundwater contamination issues. Under anoxic conditions, certain anaerobic bacteria can oxidize dissolved elemental mercury and convert the ...

Gene Expression Correlates with Process Rates Quantified for Sulfate- and Fe(III)-Reducing Bacteria in U(VI)-Contaminated Sediments [PDF]
, 2012 Though iron- and sulfate-reducing bacteria are well known for mediating uranium(VI) reduction in contaminated subsurface environments, quantifying the in situ activity of the microbial groups responsible remains a challenge.

Structure of rubredoxin from the bacterium Desulfovibrio desulfuricans [PDF]
FEBS Letters, 1986 The X‐ray crystallographic structure of rubredoxin from Desulfovibrio desulfuricans strain 27774 is described. This molecule is 15% smaller than previously studied rubredoxins, lacking a seven‐residue loop of chain but containing a histidine and a free‐sulfhydryl cysteine.

Characterization of Desulfovibrio giganteus sp. nov., a sulfate-reducing bacterium isolated from a brackish coastal lagoon [PDF]
, 1988 In the course of ecological studies in Berre Lagoon, a mediterranean brackish coastal lagoon (Marseille, France), a new slightly halophilic sulfate-reducing bacterium was isolated from anoxic sediments enriched with lactate plus sulfate, and cysteine-HCL

Effects of oxygen on the growth of Desulfovibrio desulfuricans [PDF]
Journal of General Microbiology, 1990 Summary: Desulfovibrio desulfuricans survived exposure to air on the surface of agar plates for at least 48 h. Under continuous culture conditions two effects of low oxygen partial pressures (10–15 mmHg) were noted: (1) a relief of inhibition by H2S; (2) specific inductive responses to oxygen including an increase in cell respiration (two- to threefold)

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2010 The highest catalase activity (42.67×10–2 µM×min–1×mg–1 of protein) in the cells of Desulfovibrio desulfuricans Ya-11 has been observed under the prolonged Pb(NO3)2 influence. In the presence of other heavy metals’ salts it has been changed in dependence

Stepwise isotope editing of [FeFe]-hydrogenases exposes cofactor dynamics [PDF]
, 2016 The six-iron cofactor of [FeFe]-hydrogenases (H-cluster) is the most efficient H2-forming catalyst in nature. It comprises a diiron active site with three carbon monoxide (CO) and two cyanide (CN−) ligands in the active oxidized state (Hox) and one ...
