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 ...

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

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.

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 ...

Inhibition of microbial sulfate reduction in a flow-through column system by (per)chlorate treatment. [PDF]
Microbial sulfate reduction is a primary cause of oil reservoir souring. Here we show that amendment with chlorate or perchlorate [collectively (per)chlorate] potentially resolves this issue. Triplicate packed columns inoculated with marine sediment were

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

Challenging the paradigm of metabolic exclusivity: coexistence of methanogenesis and sulfate reduction in oil reservoirs [PDF]
The prevailing dogma in microbial ecology holds that sulfate-reducing microorganisms (SRMs) outcompete methanogenic archaea for common substrates (e.g., H2/formate and acetate), leading to the mutual exclusion of sulfate reduction and methanogenesis in ...

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

Effects and Adaptive Responses of Sulfate-Reducing Biochemical System to Acid Stress [PDF]
A decrease in pH can affect the biochemical properties of a sulfate reduction system, but the stress responses to such pH fluctuations and acid-adaptive mechanisms of the microorganisms remain incompletely understood. Here, we compared the sulfate (SO42−)

Thermodynamic and kinetic response of microbial reactions to high CO2 [PDF]
Geological carbon sequestration captures CO2 from industrial sources and stores the CO2 in subsurface reservoirs, a viable strategy for mitigating global climate change.
