Eutrophication, microbial-sulfate reduction and mass extinctions [PDF]

open access: goldCommunicative & Integrative Biology, 2016
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 ...

Influence of Phosphorus and Cell Geometry on the Fractionation of Sulfur Isotopes by Several Species of Desulfovibrio during Microbial Sulfate Reduction [PDF]

open access: goldFrontiers in Microbiology, 2017
We investigated the influence of organic substrates and phosphate concentration on the rates of dissimilatory microbial sulfate reduction and the 34S/32S isotopic fractionation produced by several Desulfovibrio species.

Microbial sulfate reduction by Desulfovibrio is an important source of hydrogen sulfide from a large swine finishing facility [PDF]

open access: yesScientific Reports, 2021
There is still a lack of understanding of H2S formation in agricultural waste, which leads to poor odour prevention and control. Microbial sulfate reduction is a major process contributing to sulfide formation in natural and technogenic environments with

Oxygen isotope effects during microbial sulfate reduction: applications to sediment cell abundances. [PDF]

open access: yesISME J, 2020
The majority of anaerobic biogeochemical cycling occurs within marine sediments. To understand these processes, quantifying the distribution of active cells and gross metabolic activity is essential.

Microbial Assimilatory Sulfate Reduction-Mediated H2S: An Overlooked Role in Crohn's Disease Development [PDF]

open access: goldMicrobiome
H2S imbalances in the intestinal tract trigger Crohn's disease (CD), a chronic inflammatory gastrointestinal disorder characterized by microbiota dysbiosis and barrier dysfunction.

Microbial sulfate reduction potential in coal-bearing sediments down to ~2.5 km below the seafloor off Shimokita Peninsula, Japan [PDF]

open access: yesFrontiers in Microbiology, 2016
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 ...

Patterns of sulfur isotope fractionation during microbial sulfate reduction [PDF]

open access: greenGeobiology, 2015
Studies of microbial sulfate reduction have suggested that the magnitude of sulfur isotope fractionation varies with sulfate concentration. Small apparent sulfur isotope fractionations preserved in Archean rocks have been interpreted as suggesting ...

Integrated Plume Treatment Using Persulfate Coupled with Microbial Sulfate Reduction [PDF]

open access: hybridGroundwater Monitoring & Remediation, 2017
The integration or sequential use of different remediation technologies, also referred to as a combined remedy, has become an emerging strategy for the treatment of contaminated sites.

Effects of Sulfate Reduction on Trichloroethene Dechlorination by Dehalococcoides-Containing Microbial Communities [PDF]

open access: bronzeApplied and Environmental Microbiology, 2017
ABSTRACT In order to elucidate interactions between sulfate reduction and dechlorination, we systematically evaluated the effects of different concentrations of sulfate and sulfide on reductive dechlorination by isolates, constructed consortia, and enrichments containing Dehalococcoides sp.

Iron and sulfate reduction structure microbial communities in (sub-)Antarctic sediments [PDF]

open access: yesThe ISME Journal, 2021
Permanently cold marine sediments are heavily influenced by increased input of iron as a result of accelerated glacial melt, weathering, and erosion.
