Polysulfide as a possible substrate for sulfur-reducing bacteria

Archives of Microbiology, 1993
Because of its low solubility it is unlikely that elemental sulfur serves as the direct substrate for sulfur-reducing bacteria. To test the hypothesis that polysulfide may represent a soluble intermediate of sulfur reduction, the maximal polysulfide concentrations formed from elemental sulfur in aqueous sulfide solutions were measured at near neutral ...

Arsenite removal without thioarsenite formation in a sulfidogenic system driven by sulfur reducing bacteria under acidic conditions

Water Research, 2019
Sulfidogenic process using sulfate-reducing bacteria (SRB) has been used to remove arsenite from the arsenic-contaminated waters through the precipitation of arsenite with sulfide. However, excessive sulfide production and significant pH increase induced by sulfate reduction result in the formation of the mobile thioarsenite by-products and the ...

A survey of EPR-detectable components in sulfur-reducing bacteria

Biochimica Et Biophysica Acta - Bioenergetics, 1983
Abstract A survey was made of components of sulfur-reducing bacteria that can be detected by EPR spectroscopy. To this purpose, whole cells were examined and a membrane and cytoplasm fraction obtained by centrifugation at 120 000 × g after cell lysis by suitable procedures.
