Revisiting the dissimilatory sulfate reduction pathway
Geobiology, 2011Sulfur isotopes in the geological record integrate a combination of biological and diagenetic influences, but a key control on the ratio of sulfur isotopes in sedimentary materials is the magnitude of isotope fractionation imparted during dissimilatory sulfate reduction.

The priority pollutant antimony (Sb) exists primarily as Sb(V) and Sb(III) in natural waters, and Sb(III) is generally with greater mobility and toxicity than Sb(V). The bio-reduction of Sb(V) would not become a meaningful Sb-removal process unless the accumulation of produced dissolved Sb(III) could be controlled.

A protein trisulfide couples dissimilatory sulfate reduction to energy conservation
Science, 2015Sulfate reduction via a trisulfide Microorganisms can respire sulfur compounds in the absence of oxygen, eventually leading to the production of hydrogen sulfide. This ancient metabolism is common in modern anoxic environments, but the enzymatic pathways aren't yet fully resolved. Through in vivo and in vitro experiments, Santos

Geochimica Et Cosmochimica Acta, 2005
Abstract Sulfur isotope fractionation during dissimilatory sulfate reduction has been conceptually described by the widely accepted Rees model as related to the stepwise reduction of sulfate to sulfide within the cells of bacteria. The magnitude of isotope fractionation is determined by the interplay between different reduction steps in a chain of ...

Dissimilatory bacterial sulfate reduction in montana groundwaters
Geomicrobiology Journal, 1980Abstract The origin of hydrogen sulfide in southeastern Montana groundwaters was investigated. Sulfate‐reducing bacteria were detected in 25 of 26 groundwater samples in numbers ranging from 2.0 × 101 to greater than 2.4 × 104 bacteria per 100 ml. Stable sulfur isotope fractionation studies indicated a biological role in sulfate reduction.

Nutritional Aspects of Dissimilatory Sulfate Reduction in the Human Large Intestine
Current Microbiology, 1997 In contrast to other anaerobic ecosystems, such as marine and estuarine sediments, there is a lack of information on the nutritional requirements of human gut sulfate-reducing bacteria (SRB). Various substrates stimulated sulfate reduction in mixed culture, including short-chain fatty acids and other organic acids, alcohols, and amino acids (but not ...

Automated screening of inhibitors of bacterial dissimilatory sulfate reduction
Applied Microbiology and Biotechnology, 1991An automated assay system was used to screen inhibitors of sulfide formation by sulfate-reducing bacteria. The system used a Technicon AutoAnalyzer II instrument both as an incubation chamber (to combine bacterial cells, substrates, and test compounds) and as an analyzer of the amount of sulfide formed during incubation. A lactate-limited chemostat was

Spotting zones of dissimilatory sulfate reduction in a forested catchment: the 34S-35S approach
Environmental Pollution, 2001The localization of sulfate reducing sites in forested catchments is of major importance, because dissimilatory sulfate reduction can be a considerable sink for deposited sulfate. To localize dissimilatory sulfate reduction sites in a forested catchment (northeastern Bavaria, Germany), three sites within the catchment (upland site, intermittent seep ...

Dissimilatory Sulfate Reduction, Energetic Aspects
1981Several strict anaerobic prokaryotes are capable of using sulfate as electron acceptor for catabolic oxidation processes. In doing so sulfate is reduced to H2S (Fig. 1). Respiration with sulfate as acceptor is termed dissimilatory sulfate reduction, bacteria capable of sulfate respiration are classifled as sulfate-reducing bacteria.
