Bacterial predation limits microbial sulfate-reduction in a coastal acid sulfate soil (CASS) ecosystem

Soil Biology and Biochemistry, 2020
Abstract Microbial iron and sulfate reduction are the primary drivers of coastal acid sulfate soil (CASS) passive bioremediation schemes. Microbial sulfate reduction is the limiting step for pyrite formation, a desirable endpoint for CASS remediation.

The effects of organic matter and anaerobic oxidation of methane on the microbial sulfate reduction in cold seeps

Frontiers in Marine Science, 2023
Cold seep sediments are dominated by intensive microbial sulfate reduction coupled to anaerobic oxidation of methane. However, the contribution proportion between this process and the role of organic matter has remained enigmatic.

Active microbial sulfate reduction in fluids of serpentinizing peridotites of the continental subsurface

Communications Earth & Environment, 2021
Serpentinization of peridotites in Earth’s mantle is associated with the generation of hydrogen and low molecular weight organics that could support subsurface life.

Sulfur and Oxygen Isotope Records of Sulfate-Driven Anaerobic Oxidation of Methane in Diffusion-Dominated Marine Sediments

Frontiers in Earth Science, 2022
Organoclastic sulfate reduction (OSR) and sulfate-driven anaerobic oxidation of methane (SD-AOM) are the two major microbial pathways for sulfate consumption in marine sulfur cycle.

Impact of Organic Carbon Electron Donors on Microbial Community Development under Iron- and Sulfate-Reducing Conditions. [PDF]

PLoS ONE, 2016
Although iron- and sulfate-reducing bacteria in subsurface environments have crucial roles in biogeochemical cycling of C, Fe, and S, how specific electron donors impact the compositional structure and activity of native iron- and/or sulfate-reducing ...

Microbial sulfate reduction in littoral sediment of Lake Constance [PDF]

FEMS Microbiology Ecology, 1991
Abstract Porewater concentrations of SO 4 2− and NO 3 − , the depth distribution of FeS, FeS 2 and organically bound sulfur, and the spatial distribution and intensity of dissimilatory microbial sulfate reduction were studied at a littoral site in Lake Constance. Porewater sulfate concentrations dropped steeply from about 300 μM at the surface to

Modelling the Effects of Non-Steady State Transport Dynamics on the Sulfur and Oxygen Isotope Composition of Sulfate in Sedimentary Pore Fluids

Frontiers in Earth Science, 2021
We present the results of an isotope-enabled reactive transport model of a sediment column undergoing active microbial sulfate reduction to explore the response of the sulfur and oxygen isotopic composition of sulfate under perturbations to steady state.

Microbial sulfate reduction plays an important role at the initial stage of subseafloor sulfide mineralization

Geology, 2020
Seafloor hydrothermal deposits form when hydrothermal fluid mixes with ambient seawater, and constituent sulfide minerals are usually interpreted to precipitate abiogenically.

Modeling microbial sulfate reduction and the consequences for corrosion of copper canisters

Materials and Corrosion, 2020
The copper sulfide model (CSM) is a one‐dimensional reactive transport code for predicting the evolution of the corrosion behavior of a copper canister in a deep geological repository.
