The antiquity of microbial sulfate reduction
Earth-Science Reviews, 2004The phylogenetic positions of sulfate-reducing organisms, as revealed from comparisons of small-subunit ribosomal RNA (SSU rRNA), are spread over both the Archaeal and Bacterial domains, though when they evolved is uncertain. The low-branching positions of some of these groups on the Tree of Life have inspired the hypothesis that the metabolic ...

Microbial hydrocarbon uptake and the effect of hydrocarbons on microbial sulfate reduction
2023Guaymas Basin, located in the Gulf of California, Mexico, is a young marginal ocean basin with high sedimentation rates of >1 mm/year, active seafloor spreading, and steep geothermal gradients in its sediment. It hosts a unique subseafloor biosphere as these conditions lead to the thermal cracking of sedimentary organic matter and the production of ...

Microbial Reduction of Schwertmannite By Co-Cultured Iron- and Sulfate-Reducing Bacteria
SSRN Electronic Journal, 2022Schwertmannite (Sch) is an iron-hydroxysulfate mineral commonly found in acid mine drainage contaminated environment. The transformation mechanism of Sch mediated by pure cultured iron-reducing bacteria (FeRB) or sulfate-reducing bacteria (SRB) has been studied.

Aerobic Sulfate Reduction in Microbial Mats
Science, 1991Measurements of bacterial sulfate reduction and dissolved oxygen (O 2 ) in hypersaline bacterial mats from Baja California, Mexico, revealed that sulfate reduction occurred consistently within the well-oxygenated photosynthetic zone of the mats.

Microbial sulfate reduction decreases arsenic mobilization in flooded paddy soils with high potential for microbial Fe reduction [PDF]
Environmental Pollution, 2019 Arsenic (As) tends to mobilize in flooded paddy soil due to the reductive dissolution of the iron (oxyhydr)oxides to which As sorbs, resulting in elevated As accumulation in rice that poses a potential risk to the food safety and human health. Microbial sulfate reduction is an important biogeochemical process in paddy soils, but its impact on As ...

Water Research
Excessive sulfate levels in water bodies pose a dual threat to the ecological environment and human health. The microbial removal of sulfate encounters challenges, particularly in environments with high sulfate concentrations, where the gradual accumulation of sulfide hampers microbial activity.

Sulfate Reduction at a Lignite Seam: Microbial Abundance and Activity
Microbial Ecology, 2001In a combined isotope geochemical and microbiological investigation, a setting of multiple aquifers was characterized. Biologically mediated redox processes were observed in the aquifers situated in marine sands of Tertiary age and overlying Quaternary gravel deposits.

Microbial sulfate reduction in a liquid–solid fluidized bed reactor
Biotechnology and Bioengineering, 2000A liquid-solid fluidized bed reactor was used to carry out sulfate reduction with a mixed culture of sulfate reducing bacteria. The bacteria were immobilized on porous glass beads. Stable fluidized bed operation with these biofilm-coated beads was possible.

Kinetics of microbial sulfate reduction in estuarine sediments
Geochimica et Cosmochimica Acta, 2006Abstract Kinetic parameters of microbial sulfate reduction in intertidal sediments from a freshwater, brackish and marine site of the Scheldt estuary (Belgium, the Netherlands) were determined. Sulfate reduction rates (SRR) were measured at 10, 21, and 30 °C, using both flow-through reactors containing intact sediment slices and conventional sediment
