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 …

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, …

Effect of polysulfides on cinnabar solubility, partitioning, and methylation by Desulfovibrio desufuricans
Sulfate reducing bacteria are believed to be the most important methylators of mercury in aquatic systems. Methylation may be controlled by the availability of mercury to these bacteria and therefore may depend on mercury speciation in sulfidic water ...

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 …

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 …

Effects of macromolecular crowding and small ions on the folding, structure, and stability of Desulfovibrio desufuricans flavodoxin
… the biophysical properties of a model protein -- Desulfovibrio desulfuricans flavodoxin. Flavodoxin is a small (15.7 kDa), single domain, cytoplasmic protein with alpha-helical and parallel beta-sheet secondary structural elements arranged in one of the five most common protein folds (the …

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 …

Biofilm formation on metal surfaces
… bacterial species Pseudomonas fluorescens and Desulfovibrio desulfuricans and the role of these biofilms in corrosion of steel has been investigated. Early events leading to the formation of biofilms have been elucidated by studying the attachment of bacterial cells to steel using …

Linking microbial community dynamics and performance of a biological sulphate reducing system using a mixed volatile fatty acid stream as electron donor
… SRB species belonging to the Desulfomicrobium, Desulfovibrio, Desulfuromonas, Desulfobulbus and Desulfocurvus genera. Other “non-traditional SRB” species belonging to the Firmicutes and Citrobacter genera containing a specific molecular target for the detection of SRBs, the dissimilatory …

Isolation and Characterization of Syntrophomonas Wolfeii, a New Anaerobic, Syntrophic, Fatty Acid-Oxidizing Bacterium
… non-fatty acid-degrading, hydrogen-utilizing Desulfovibrio species or methanogenic bacteria. Three strains of this new bacterium obtained from different environmental sources were characterized and are herein described as a new genus and species Syntrophomonas wolfeii.

A biochemical and physiological characterization of coenzyme F420-reducing hydrogenase from Methanobacterium formicicum
… from Methanobacterium thermoautotrophicum, Desulfovibrio baculatus, and Desulfovibrio gigag. FAD dissociated from the coenzyme F42O-reducing hydrogenase during reactivation with H2 and coenzyme F₄₂₀, unless KCl was present, yielding coenzyme F₄₂₀-inactive apoenzyme. The hydrogenase catalyzed …

Engineered Oligosaccharyltransferases With Unique N-Glycosylation Site Preferences
… We provided a thorough investigation into Desulfovibrio desulfuricans PglB (DdPglB), an OST sharing homology with C. jejuni PglB but having more relaxed sequon specificity. The sequon logo of DdPglB against XXNXT library were built through a high-throughput assay. Two engineered OSTs …

A Bioinformatics Analysis of Bacterial Type-III Secretion System Genes and Proteins
… comprehensive re-annotation of T3SS loci within Desulfovibrio, Lawsonia and Hahella, and subsequent comparison of these T3SSs with related Yersinial T3SSs, and also (in conjunction with in vitro assays) for identification of many novel effectors in E. coli.
