Molybdenum Isotope Fingerprinting of Microbial Sulfate Reduction in Seep Carbonate Rocks [PDF]

open access: diamondGeochemistry, Geophysics, Geosystems
Understanding the interaction between molybdenum (Mo) and organic matter during microbial sulfate reduction is critical for the use of Mo to reconstruct marine redox conditions throughout Earth's history.

INHIBITION OF MICROBIAL SULFATE REDUCTION BY MOLYBDATE

open access: yesBrazilian Journal of Petroleum and Gas, 2015
Hydrogen sulfide generation in oil production is a constant cause of concern. In several cases this phenomenon occurs due to the action of sulfate-reducing bacteria. Various methods, including biocides and nitrate addition, have been used to control the activity of these microorganisms, but they are expensive and have side effects.

Microbial sulfate reduction and metal attenuation in pH 4 acid mine water [PDF]

open access: goldGeochemical Transactions, 2007
AbstractSediments recovered from the flooded mine workings of the Penn Mine, a Cu-Zn mine abandoned since the early 1960s, were cultured for anaerobic bacteria over a range of pH (4.0 to 7.5). The molecular biology of sediments and cultures was studied to determine whether sulfate-reducing bacteria (SRB) were active in moderately acidic conditions ...

Characterizing the distribution and rates of microbial sulfate reduction at Middle Valley hydrothermal vents [PDF]

open access: bronzeThe ISME Journal, 2013
Few studies have directly measured sulfate reduction at hydrothermal vents, and relatively little is known about how environmental or ecological factors influence rates of sulfate reduction in vent environments.

Microbial hydrocarbon uptake and the effect of hydrocarbons on microbial sulfate reduction

open access: gold, 2023
Guaymas 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 ...

Thermophilic and mesophilic sulfate reduction by rare biosphere bacteria in acidic metal-bearing mine wastes from the temperate climate zone [PDF]

open access: yesScientific Reports
Dissimilatory sulfate reduction is the main microbial process that detoxifies metals and increases pH in acid mine drainage. Acidophilic, copper-resistant Desulfosporosinus sp. BG and Desulfosporosinus sp.

Sulfate reduction and homoacetogenesis at various hypersaline conditions: Implications for H2 underground gas storage

open access: yesFrontiers in Energy Research, 2023
While interest in underground gas storage (UGS) of hydrogen (H2) in salt caverns is increasing in a growing H2 economy, knowledge of the microbial communities inhabiting those hypersaline environments is still scarce. High salt concentrations and limited

Cryptic sulfur cycling in the deep biosphere of ferruginous Lake Towuti, Indonesia [PDF]

open access: yesFrontiers in Microbiology
Lake Towuti, Sulawesi, Indonesia is an ancient tectonic lake, exhibiting iron-rich, sulfate-poor anoxic deep waters. Temporal variations in water column stratification led to sediment accumulation under variable redox conditions.
