[Sulfate-reducing bacteria in reservoirs of the Yavoriv sulfur field].

Mikrobiolohichnyi zhurnal (Kiev, Ukraine : 1993), 2007
Fifteen cultures of bacteria which perform dissimilation sulfate reduction have been isolated from the reservoirs of the Yavoriv sulfur deposit. Electron-microscopic investigations have shown that the cells of all cultures are of vibroid, spiral and bacillary form. They form no spores.

Microbial Recovery of Sulfur from Thiosulfate-Bearing Wastewater with Phototrophic and Sulfur-Reducing Bacteria

Current Microbiology, 1996
The spent caustic wastewater from the oxidation of sulfide present in offshore natural gas production mainly comprises thiosulfate and sulfate. A biocatalytic process, employing phototrophic green sulfur bacteria in symbiosis with sulfate-reducing bacteria, is described in this paper for the production of sulfur from the spent caustic wastewater, with ...

Role of sulfur-reducing bacteria in a wetland system treating acid mine drainage

Science of The Total Environment, 2008
This 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,

Transcriptional analysis of sulfate reducing and chemolithoautotrophic sulfur oxidizing bacteria in the deep subseafloor

Environmental Microbiology Reports, 2016
Summary Sulfate reducing bacteria (SRB) oxidize a significant proportion of subseafloor organic carbon, but their metabolic activities and subsistence mechanisms are poorly understood.

Reducing Pollution, Restoring Balance: The Microbiology of Sulfur‐Reducing Bacteria in Textile Wastewater Treatment

Journal of Basic Microbiology
ABSTRACT The textile industry releases large volumes of harmful chemicals, including residual dyes and xenobiotics—synthetic or foreign compounds not naturally produced or expected in living systems, such as dyes, surfactants, and pesticides.

Sulfur cycling in mixed cultures of sulfide-oxidizing and sulfate- or sulfur-reducing oil field bacteria

Canadian Journal of Microbiology, 1999
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

The Role of Sulfate-Reducing and Sulfur-Oxidizing Bacteria on Localized Corrosion

CORROSION 1983, 1983
Abstract 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

Sulfate-reducing bacteria and sulfur-oxidizing bacteria interactions at redox interfaces: Implications for mercury methylation

Environmental Research
Methylmercury (MeHg), the most neurotoxic and bioaccumulative mercury (Hg) species, poses significant risks to human and ecosystem health. Predicting these risks requires elucidating the drivers of MeHg production, which peaks at redox interfaces in aquatic systems where the primary Hg methylators, sulfate-reducing bacteria (SRB), are most active ...

Biosynthesis of semiconductor nanoparticles by using sulfur reducing bacteria Serratia nematodiphila

Advances in nano research, 2013
The synthesis of semiconductor nanoparticles is a growing research area due to the prospective applications for the development of novel technologies. In this paper we have reported the biosynthesis of Cadmium sulfide nanoparticles (CdSNPs) by reduction of cadmium sulphate solution, using the bacteria of Serratia nematodiphila.

Simple and Complex Iron-Sulfur Proteins in Sulfate Reducing Bacteria

1999
Publisher 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 ...
