Eutrophication, microbial-sulfate reduction and mass extinctions [PDF]
In post-Cambrian time, life on Earth experienced 5 major extinction events, likely instigated by adverse environmental conditions. Biodiversity loss among marine taxa, for at least 3 of these mass extinction events (Late Devonian, end-Permian and end ...

Microbial sulfate reduction potential in coal-bearing sediments down to ~2.5 km below the seafloor off Shimokita Peninsula, Japan [PDF]
Sulfate reduction is the predominant anaerobic microbial process of organic matter mineralization in marine sediments, with recent studies revealing that sulfate reduction not only occurs in sulfate-rich sediments, but even extends to deeper ...

Dissimilatory sulfate reduction in the intestinal sulfate-reducing bacteria
The study of the intestinal sulfate-reducing bacteria, the process of dissimilatory sulfate reduction and accumulation of hydrogen sulfide, as well as their role in the inflammatory bowel diseases, including ulcerative colitis, in animals and human have ...

Coexistence of methanogenesis and sulfate reduction in a sulfate-adapted enrichment culture from an oil reservoir [PDF]
Oil reservoirs are complex ecosystems where microorganisms play a vital role in hydrocarbon degradation, mostly with methanogenesis as the terminal electron-accepting process. Especially in offshore oil reservoirs, sulfate-containing seawater is injected

Cell-specific rates of sulfate reduction and fermentation in the sub-seafloor biosphere [PDF]
Microorganisms in subsurface sediments live from recalcitrant organic matter deposited thousands or millions of years ago. Their catabolic activities are low, but the deep biosphere is of global importance due to its volume.

Recent Advances in Metabolic Pathways of Sulfate Reduction in Intestinal Bacteria [PDF]
Sulfate is present in foods, beverages, and drinking water. Its reduction and concentration in the gut depend on the intestinal microbiome activity, especially sulfate-reducing bacteria (SRB), which can be involved in inflammatory bowel disease (IBD ...

Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter. [PDF]
Sulfate reduction plays an important role in altering dissolved organic matter (DOM) in estuarine and coastal sediments, although its role in the production of optically active chromophoric DOM (CDOM) and a subset of fluorescent DOM (FDOM) has not been ...

Multiple sulfur isotope signatures of sulfite and thiosulfate reduction by the model dissimilatory sulfate-reducer, Desulfovibrio alaskensis str. G20 [PDF]
Dissimilatory sulfate reduction serves as a key metabolic carbon remineralization process in anoxic marine environments. Sulfate reducing microorganisms can impart a wide range in mass-dependent sulfur isotopic fractionation.
