Isotope fractionation and sulfur metabolism by pure and enrichment cultures of elemental sulfur-disproportionating bacteria [PDF]
, 1998 We have explored the sulfur metabolism and accompanying fractionation of sulfur isotopes during the disproportionation of elemental sulfur by seven different enrichments and three pure bacterial cultures.

Investigation of Elemental Sulfur Corrosion Mechanisms [PDF]
, 2020 Sour gas wells frequently co-produce elemental sulfur which can cause catastrophic corrosion of mild steel. As producing wells become increasingly sour, the incidence of sulfur corrosion will likely increase. Despite the severity of this problem, limited

Microscopic interaction of single atomic elemental Hg with a sulfur surface [PDF]
, 2016 In preparation of chemical investigations of the superheavy elements (SHEs) copernicium and flerovium, model experiments with 197Hg were conducted. The interaction of elemental mercury on a sulfur surface was investigated by off-line isothermal gas ...

Influence of soil minerals on chromium(VI) reduction by sulfide under anoxic conditions
Geochemical Transactions, 2007 The effects of soil minerals on chromate (CrVIO42-, noted as Cr(VI)) reduction by sulfide were investigated in the pH range of 7.67 to 9.07 under the anoxic condition. The examined minerals included montmorillonite (Swy-2), illite (IMt-2), kaolinite (KGa-

Bioleaching of Metals from Sewage Sludge: Elemental Sulfur Recovery. [PDF]
, 1994 Heavy metal leaching by sulfur‐oxidizing bacteria, one of the most promising sludge detoxification methods, uses elemental sulfur as a microbial energy substrate.

The effect of different sulfur doses and forms on changes of soil heavy metals
Plant, Soil and Environment, 2012 A three-year field experiment was conducted in North-East Poland. Each year three sulfur fertilization rates in the form of sulphate (S-SO42-) and pure (S-S0) sulfur were applied: 40, 80, and 120 kg/ha.

Isolation of a putative sulfur comproportionating microorganism
Scientific ReportsSulfur comproportionation, the coupled oxidation of sulfide and reduction of sulfate to elemental sulfur, is a heretofore undiscovered microbial catabolism that has been predicted based on thermodynamic calculations.

Flotation extraction of elemental sulfur from gold-bearing cakes
Записки Горного института, 2020 Currently, in the development of the raw materials base of the gold mining industry, there is a tendency to reduce the quality of the initial mineral raw materials due to the depletion of reserves of rich gold-bearing ores.
