Microsites support microbial sulfate reduction in upland soils
Soil Biology and BiochemistryAgricultural sulfur (S) inputs are a primary source of anthropogenic S to the environment, often stimulating microbial sulfate reduction (MSR) in downstream environments and driving multiple ecosystem consequences. Because it is assumed that bulk oxygenated soils do not support reduction processes, MSR is typically only studied in saturated ...

Large sulfur isotope fractionations associated with Neoarchean microbial sulfate reduction
Science, 2014Dissecting ancient microbial sulfur cycling Before the rise of oxygen, life on Earth depended on the marine sulfur cycle. The fractionation of different sulfur isotopes provides clues to which biogeochemical cycles were active long ago (see the Perspective by Ueno). Zhelezinskaia et al.

Marine Pollution Bulletin, 2011
The bacterial communities in the anoxic layer of a heavily polluted microbial mat and their growth on hydrocarbons under sulfate-reducing conditions were investigated. Microbial communities were dominated by members of Alphaproteobacteria (27% of the total rRNA), Planctomycetes (21.1%) and sulfate-reducing bacteria (SRB: 17.5%).

The impact of microbial sulfate-reduction on subsurface arsenic mobility
2012Sulfate-reducing bacteria are ubiquitous in subsurface soils, sediments and groundwater systems. These bacteria couple the anaerobic oxidation of organic carbon (C) or hydrogen (H2) with the reduction of sulfate (SO42−). This results in the generation of sulfide; a powerful reductant that can drive the reductive dissolution of ferric (hydr)oxides.

Microbial sulfate reduction measured by an automated electrical impedance technique
Geomicrobiology Journal, 1979Electrical impedance measurements are used to investigate the rates of sulfate reduction by pure cultures of and sediments containing sulfur-reducing bacteria. Changes in the electrical impedance ratios of pure cultures of Desulfovibrio aestuarii and samples of reduced sediments from San Francisco Bay were measured by a Bactometer 32, and sulfate ...

Iron-carbon micro-electrolysis enhances microbial sulfate reduction and sulfur recovery
Journal of Environmental ManagementAddressing the challenges of unstable activity in microbial sulfate-reducing bacteria (SRB) and the need for further recovery of sulfate reduction products, this study employed iron-carbon (Fe-C) micro-electrolysis to enhance microbial sulfate reduction (MSR) and achieve sulfur resource recovery.

Sulfidation of Cd-Sch During the Microbial Sulfate Reduction: Nanoscale Redistribution of Cd
Science of The Total EnvironmentSchwertmannite (Sch) is found in environments abundant in iron and sulfate. Microorganisms that utilize iron or sulfate can induce the phase transition of Schwertmannite, consequently leading to the redistribution of coexisting pollutants. However, the impact of the molar ratio of sulfate to iron (S/Fe) on the microbial-mediated transformation of ...
