Sulfate-Reducing Bacteria Lower Sulfur-Mediated Pitting Corrosion under Conditions of Oxygen Ingress
Environmental Science & Technology, 2012The effect of oxygen ingress into sour water containing dissolved sulfide on the production of sulfur and polysulfide (S-PS) and associated iron corrosion was investigated. Biotic (active SRB present), abiotic (autoclaved SRB present), and chemical (no bacteria present) conditions were compared.

Role of sulfur-reducing bacteria in a wetland system treating acid mine drainage
Science of The Total Environment, 2008This report describes a twenty month case study of a successive alkalinity producing system (SAPS) treating a strong acid mine drainage (AMD) source in Coshocton County, Ohio. Prior to the commencement of the project, a large volume of black amorphous sludge had accumulated in several of the constructed wetlands. The sludge was found to be 43% organic,

[24] Sulfur reductase from thiophilic sulfate-reducing bacteria
1994Publisher Summary This chapter describes purification and characterization of the sulfur reductase from Desulfomicrobium . baculatum Norway 4. It also discusses oxidative phosphorylation coupled to the dissimilatory reduction of colloidal sulfur by Desulfovibrio. gigas.

Simple and Complex Iron-Sulfur Proteins in Sulfate Reducing Bacteria
1999Publisher Summary This chapter focuses on simple and complex iron–sulfur-containing proteins isolated from sulfate reducing bacteria (SRB), to review the types and distribution of proteins, metal clusters involved and their association with other centers and cofactors, cluster binding motifs, electronic and magnetic properties of the iron-sulfur ...

Thiomicrospira strain CVO and Arcobacter strain FWKO B are two nitrate-reducing, sulfide-oxidizing bacteria (NR-SOB) isolated from the Coleville field in western Canada. Analysis by reverse sample genome probing (RSGP) indicates that both can be enriched from Coleville produced water samples by addition of nitrate. Neither could be enriched from waters

Electric current generation by sulfur-reducing bacteria in microbial-anode fuel cell
SPIE Proceedings, 2012Sulfur - reducing bacteria are a part of normal microflora of natural environment. Their main function is supporting of reductive stage of sulfur cycle by hydrogen sulfide production in the process of dissimilative sulfur-reduction. At the same time these bacteria completely oxidize organic compounds with CO 2 and H 2 O formation.

The Role of Sulfate-Reducing and Sulfur-Oxidizing Bacteria on Localized Corrosion
CORROSION 1983, 1983Abstract Chemical and microbiological interactions of inorganic sulfur compounds, which result in the formation of various aggressive sulfoanions such as sulfide, sulfite, thiosulfate, and tetrathionate, etc. will be reviewed with emphasis on the catalytic role played in these transformations by exposed metal surfaces and traces of metal
