An analysis of the outer membrane of desulfovibrio vulgaris (Woolwich)
D.vulgaris (Woolwich) OMs can be extracted successfully and reproducibly from the cell envelopes by the selective solubilisation of cell membranes by sarkosyl. Three Omps (Omps 1, 2 & 3) occur consistently in the OMs of C-Fe, NC & C+Fe cells. NC C+Fe OMs have, in addition, minor proteins absent …

Identification and characterization of novel small RNAs in Desulfovibrio vulgaris Hildenborough
<italic>Desulfovibrio vulgaris</italic> strain Hildenborough is a key organism in the bioremediation of environments contaminated with anthropogenic sources of heavy metals and radionuclides. In order for <italic>D. vulgaris</italic> to be optimized for remediation of such sites in the environment, …

CHARACTERIZATION OF A DUAL FUNCTIONING SAM-I RIBOSWITCH AND TRANS ACTING SMALL RNA IN DESULFOVIBRIO VULGARIS HILDENBOROUGH
<italic>Desulfovibrio vulgaris</italic> Hildenborough (<italic>Dv</italic>H) is a sulfate-reducing bacterium that has the potential to be an agent of bioremediation by aiding in the precipitation of heavy metals and radionuclides from contaminated environments via its natural metabolism. Because …

Quantifying the expression of dissimilatory sulfite reductase as a metric for sulfate reduction rates
… of sulfate reduction in natural systems. We grew Desulfovibrio vulgaris in fed-batch reactors under electron-donor limiting conditions. To simulate conditions characteristic of oligotrophic environments such as anoxic aquifers, we constrained the rates of sulfate reduction from 0.1 μM h–1 to 20 μM …

Estudio de procesos para la solubilización y precipitación de iones metálicos contaminantes mediante bacterias azufre-oxidantes y sulfatoreductoras
… compounds. Sulphate-reducing bacteria, the genus Desulfovibrio, are able to carry out this kind of processes.The integration of both processes allows the solubilization of heavy metal from insoluble compounds of contaminated media and then can be precipitated as insoluble compounds again which can …

A revised monod-type rate law predicting variable sulfur isotope fractionation factors as a function of microbial sulfate reduction rate
… of batch reactors containing an identical amount Desulfovibrio vulgaris, a strain of sulfate reducing bacteria (SRB), were subjected to differing continuous mass addition rates of formate to minimize growth and control the rate of sulfate reduction via electron donor limitation. The isotopic …

An investigation into the structure and functional aspects of the cell wall of Desulfovibrio
Satisfactory preparations of cell walls from Desulfovibrio vulgaris cells grown in iron rich (C+Fe) and iron poor (C-Fe) media were obtained by partial detergent solubilisation of the cell envelopes. Polyacrylamide gel electrophoresis (PAGE) has shown the presence in the outer membrane (OM) of …

Structural enzymology of bacterial carbon fixation and storage
… determined crystal structures of the CODH from Desulfovibrio vulgaris revealing that a solvent-exposed iron-sulfur cluster in the enzyme is a critical contributor to irreversible oxidative damage and that damage can be avoided through variations in cluster type at this position. In a separate …

Physiology of multiple sulfur isotope fractionation during microbial sulfate reduction
… investigated in cultures of mutant strains of Desulfovibrio vulgaris Hildenborough. The mutant lacking Type I tetraheme cytochrome c₃ fractionated ³⁴S/³²S ratio 50% greater relative to the wild type. The increasing S-isotope fractionation accompanied the evolution of H2 in the headspace and the …

A Study of Peroxide Resistance in the Microaerophile, Spirillum volutans
… in the anaerobes Clostridium perfringens and Desulfovibrio vulgaris and to putative rubrerythrin proteins found in some anaerobic archeons. This is the first report of this type of protein in an organism that must respire with oxygen. This rubreythrin-like protein may play a role in the …

Nitrate and nitrite growth inhibition of Desulfovibrio strains
… of the model sulfate-reducing bacteria, Desulfovibrio vulgaris Hildenborough and Desulfovibrio alaskensis G20, to nitrate and nitrite were studied. We found that mutations that inactivate the functions of a small number of genes cause nitrate resistance in these bacteria. These mutations …

Low strength wastewater treatment using emerging anaerobic treatment processes
… time to show the electricity generation by using Desulfovibrio vulgaris Hildenborough (DvH) in such a MFC configuration. Electron microscopic analysis indicated that nanoscale filaments could enhance the extracellular electron transfer of DvH. DvH biofilm, which is necessary for extracellular …
