Dissimilatory arsenate and sulfate reduction in Desulfotomaculum auripigmentum sp. nov.
Archives of Microbiology, 1997A newly discovered arsenate-reducing bacterium, strain OREX-4, differed significantly from strains MIT-13 and SES-3, the previously described arsenate-reducing isolates, which grew on nitrate but not on sulfate. In contrast, strain OREX-4 did not respire nitrate but grew on lactate, with either arsenate or sulfate serving as the electron acceptor, and ...

Abstract Although dissimilatory iron and sulfate reduction (DIR and DSR) profoundly affect the biogeochemical cycling of C, Fe, and S in subsurface systems, the dynamics of DIR and DSR in the presence of both FeIII (hydr)oxides and sulfate have not been well-studied with mixed microbial populations.

Generation of zero valent sulfur from dissimilatory sulfate reduction under methanogenic conditions
Journal of Hazardous Materials, 2019 Dissimilatory sulfate reduction mediated by sulfate-reducing microorganisms (SRMs) has a pivotal role in the sulfur cycle, from which the generation of zero valent sulfur (ZVS) represents a novel pathway. Nonetheless, information on ZVS production from the dissimilatory sulfate reduction remains scarce. This study successfully showed the ZVS production

Dissimilatory Sulfate Reduction, Mechanistic Aspects
1981Dissimilatory sulfate-reducing bacteria, belonging to the genera Desulfovibrio and Desulfotomaculum can carry out the process of anaerobic respiration by utilizing inorganic sulfate as a terminal electron acceptor. The overall process of dissimilatory sulfate reduction may be considered to occur in two phases.

In this study, a novel approach was developed for sulfate - containing wastewater treatment via dosing Fe₂O₃ in a two - stage anaerobic reactor (A1, S1). The addition of Fe₂O₃ in its second stage i.e. acidogenic sulfate-reducing reactor (S1) resulted in microbial reduction of Fe (III), which significantly enhanced the biological sulfate reduction.

Dissimilatory sulfate reduction in hypersaline coastal pans: Activity across a salinity gradient
Geochimica et Cosmochimica Acta, 2007The impact of salinity on the metabolic activity of sulfate-reducing bacteria in five highly saline to hypersaline coastal pans was studied using a radioactive tracer ð 35 SO4 2 Þ technique. We recorded sulfate reduction at in situ porewater salinities of up to 422.

Geochimica et Cosmochimica Acta, 2008 Abstract The stable isotopes of sulfate are often used as a tool to assess bacterial sulfate reduction on the macro scale. However, the mechanisms of stable isotope fractionation of sulfur and oxygen at the enzymatic level are not yet fully understood.

Enzymatic reactions during dissimilatory sulfate reduction (DSR) are often treated as unidirectional with respect to dissolved sulfide. However, quantitative models describing kinetic sulfur isotope fractionations during DSR consider the individual enzymatic reactions as reversible (Rees, 1973).

Sulfur is an essential element for the synthesis of cysteine, methionine, and other organo-sulfur compounds needed by living organisms. Additionally, some prokaryotes are capable of exploiting oxidation or reduction of inorganic sulfur compounds to energize cellular growth. Several anaerobic genera of Bacteria and Archaea produce hydrogen sulfide (H2S),
