Dissimilatory sulfite reductase (dSiR, DsrAB) is a key protein in dissimilatory sulfur metabolism, one of the earliest types of energy metabolism to be traced on earth. dSirs are large oligomeric proteins around 200kDa forming an alpha(2)beta(2) arrangement and including a unique siroheme-[4Fe-4S] coupled cofactor.

The characterization of sulfate-reducing bacteria (SRBs) is presented using the dissimilatory sulfite reductase (dsrAB) gene from various samples capable of mineralizing petroleum components. These samples include several novel, sulfidogenic pure cultures which degrade alkanes, toluene, and tribromophenol.

Microbial Ecology, 2005
By combining molecular biology and biochemical approaches, the dynamics of sulfate-reducing microorganisms (SRM) was investigated in the sediments of the Seine estuary (France). Both intertidal mixing-zone and freshwater mudflats were sampled during a 1-year period; the quantification of SRM was realized by using competitive polymerase chain reaction ...

International Biodeterioration and Biodegradation, 2013
Abstract Microbial sulfate reduction, an important metabolic process in petroleum reservoirs, is widely known as a major contributor to microbial influenced corrosion and deterioration of oil quality. To better control oil field corrosion and oil degradation caused by the sulfate-reducing bacteria (SRBs), the community structure and composition of ...

Dissimilatory Sulfite Reductase (dSiR) is the main redox enzyme system utilized in sulfur metabolism in both sulfur oxidizing and reducing prokaryotes. Anoxygenic phototrophic bacteria Allochromatium vinosum produces elemental sulfur during sulfur cycle which is ultimately oxidized sulfate by DSR operon.

Sulfate reduction is the most important process involved in the mineralization of carbon in the anoxic bottom waters of Mono Lake, an alkaline, hypersaline, meromictic Lake in California. Another important biogeochemical process in Mono Lake is thought to be sulfate-dependent methane oxidation (SDMO).

Expression of dsrAB in Desulfotalea psychrophila Subjected to Simulated Martian Conditions
2019For years the debate about the possible contamination of space and other planets with microbes from Earth has been a hot topic. Furthermore, the discovery of sulfate minerals on the Martian surface make this planet suitable to colonization by microorganisms adapted to survive and grow under earthly extreme conditions.

Sulfate-reducing bacteria (SRB) are important regulators of a variety of processes in coastal marine sediments regarding organic matter turnover, biodegradation of pollutants, and sulfur and carbon cycles. Yet their community compositions have not been investigated in polluted harbor sediments.

Spatial relationships between concentrations of Cd, Fe, Mn, S, and Zn and bacterial genes for dissimilatory sulfate reduction were studied in soils of the Manning peatland region in western New York. Peat cores were collected within a field exhibiting areas of Zn phytotoxicity, and pH and elemental concentrations were determined with depth.
