Dissecting ancient microbial sulfur cycling Before the rise of oxygen, life on Earth depended on the marine sulfur cycle. The fractionation of different sulfur isotopes provides clues to which biogeochemical cycles were active long ago (see the Perspective by Ueno). Zhelezinskaia et al. found negative isotope anomalies in Archean rocks from Brazil and posit that metabolic fluxes from sulfate-reducing microorganisms influenced the global sulfur cycle, including sulfur in the atmosphere.

Organic sulfur was integral to the Archean sulfur cycle
TLDR
It is argued that organic sulfur cycling may have played a previously unrecognized, yet important, role in the formation of ancient Archean marine sulfides, and offers an alternative explanation for the low range of δ34S in Archean sulfides. Expand
Sulfide oxidation affects the preservation of sulfur isotope signals
The accumulation of oxygen in Earth’s atmosphere and oceans in the late Archean had profound implications for the planet’s biogeochemical evolution. Oxygen impacts sulfur cycling through theExpand
The Biogeochemical Sulfur Cycle of Marine Sediments
TLDR
The progress and current status in the understanding of the sulfur cycle in the seabed with respect to its microbial ecology, biogeochemistry, and isotope geochemistry are reviewed. Expand
Microscale reservoir effects on microbial sulfur isotope fractionation
Microbial sulfate reduction can impart strong sulfur isotope fractionation by preferentially using the lighter 32SO42- over the heavier 34SO42-. The magnitude of fractionation depends on a number ofExpand
Rethinking the Ancient Sulfur Cycle
The sulfur biogeochemical cycle integrates the metabolic activity of multiple microbial pathways (e.g., sulfate reduction, disproportionation, and sulfide oxidation) along with abiotic reactions andExpand

Abstract Calibration of ancient marine sulfate levels has been done largely using experimental studies of the kinetic isotope effect associated with microbial sulfate reduction and work from modernExpand
Role of APS reductase in biogeochemical sulfur isotope fractionation
TLDR
The isotope effect of the first reductive enzyme in the sulfate respiration pathway is determined and sedimentary S-isotope records are reinterpreted based on this biochemical constraint. Expand
Multiple sulfur isotope signature of early Archean oceanic crust, Isua (SW-Greenland)
Abstract The Archean sulfur cycle was different from the present-day cycle, as the emission of volcanogenic sulfurous gases was the dominant process in the anoxic environment of the early Earth.ThisExpand
Sulfur and oxygen isotope insight into microbial sulfurmetabolism
Dissimilatory microbial sulfate reduction (MSR) is a process where microbes utilize sulfate as an electron acceptor to oxidize organic matter in anoxic environments. In modern marine sediments, MSRExpand
Multiple sulfur isotope constraints on microbial sulfate reduction below an Archean seafloor hydrothermal system
TLDR
The quadruple sulfur isotopic compositions of sulfide minerals within hydrothermally altered seafloor basalt and less altered basaltic komatiite collected from the North Pole Dome area imply the involvement of biological sulfate reduction processes, both in the hydrothermal system below the seafl floor and in less altered subsurface settings.

TLDR
A detailed model of the marine sulfur cycle is used to propagate and distribute atmospherically derived S MIF from its delivery to the ocean to its preservation in the sediment, which is predicted to be most highly variable in nonmarine and shallow-water settings. Expand

Influence of sulfate reduction rates on the Phanerozoic sulfur isotope record
TLDR
Experiments linking the magnitude of fractionations of the multiple sulfur isotopes to the rate of microbial sulfate reduction demonstrate that such fractionations are controlled by the availability of electron donor (organic matter), rather than by the concentration of electron acceptor (sulfate), an environmental constraint that varies among sedimentary burial environments.

TLDR
Using an integrated biogeochemical model of the Archean sulfur cycle, it is found that the preservation of mass-independent sulfur is influenced by a variety of extra-atmospheric mechanisms, including biological activity and continental crust formation. Expand
