Inhibition of microbial sulfate reduction in a flow-through column system by (per)chlorate treatment. [PDF]

Front Microbiol, 2014
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

Treatment of Acid Mine Drainage in a Bioelectrochemical System, Based on an Anodic Microbial Sulfate Reduction [PDF]

Journal of Ecological Engineering, 2023
The possibilities of simultaneous removal of sulfates and heavy metals (Cu, Ni, Zn) from acid mine drainage have been investigated in two-section bioelectrochemical system (BES).

Microbial sulfate reduction and organic sulfur formation in sinking marine particles [PDF]

Science, 2020
Where they can't breathe Climate warming is causing the expansion of marine oxygen-deficient zones, which are regions in which dissolved oxygen concentrations are so low that many marine animals cannot survive.

Coexistence of methanogenesis and sulfate reduction in a sulfate-adapted enrichment culture from an oil reservoir [PDF]

Applied and Environmental Microbiology
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

Unprecedented ³⁴S‐enrichment of pyrite formed following microbial sulfate reduction in fractured crystalline rocks [PDF]

Geobiology, 2018
In the deep biosphere, microbial sulfate reduction (MSR) is exploited for energy. Here, we show that, in fractured continental crystalline bedrock in three areas in Sweden, this process produced sulfide that reacted with iron to form pyrite extremely ...

Hydrothermal activity fuels microbial sulfate reduction in deep and distal marine settings along the Arctic Mid Ocean Ridges [PDF]

Frontiers in Marine Science
Microbial sulfate reduction is generally limited in the deep sea compared to shallower marine environments, but cold seeps and hydrothermal systems are considered an exception.

Microbial Manganese and Sulfate Reduction in Black Sea Shelf Sediments [PDF]

Applied and Environmental Microbiology, 2000
ABSTRACT The microbial ecology of anaerobic carbon oxidation processes was investigated in Black Sea shelf sediments from mid-shelf with well-oxygenated bottom water to the oxic-anoxic chemocline at the shelf-break. At all stations, organic carbon (C org ) oxidation rates were rapidly attenuated with depth

Rates of sulfate reduction and thiosulfate consumption in a marine microbial mat [PDF]

FEMS Microbiology Letters, 1992
The sulfur cycle in a microbial mat was studied by determining viable counts of sulfate-reducing bacteria, chemolithoautotrophic sulfur bacteria and anoxygenic phototrophic bacteria. All three functional groups of sulfur bacteria revealed a maximum population density in the uppermost 5 mm of the mat: 1.1 X 10(8) cells of sulfate reducers cm-3 sediment,

Multiple sulfur isotope signatures of sulfite and thiosulfate reduction by the model dissimilatory sulfate-reducer, Desulfovibrio alaskensis str. G20 [PDF]

Frontiers in Microbiology, 2014
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.

Thermodynamic and kinetic response of microbial reactions to high CO2 [PDF]

Frontiers in Microbiology, 2016
Geological carbon sequestration captures CO2 from industrial sources and stores the CO2 in subsurface reservoirs, a viable strategy for mitigating global climate change.
