Rethinking the Ancient Sulfur Cycle
TL;DR: In this article, the deep-time δ34S record of marine sulfates and sulfides is reviewed in light of recent advances in understanding the sulfur biogeochemical cycle.
Journal ArticleDOI
Influence of sulfate reduction rates on the Phanerozoic sulfur isotope record
TL;DR: 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.

Rapid oxygenation of Earth’s atmosphere 2.33 billion years ago
Genming Luo,Genming Luo,Shuhei Ono,Nicolas J. Beukes,David T. Wang,Shucheng Xie,Roger E. Summons +6 more
TL;DR: The new data suggest that the oxygenation occurred rapidly—within 1 to 10 million years—and was followed by a slower rise in the ocean sulfate inventory, whereas the relationships among GOE, “Snowball Earth” glaciation, and biogeochemical cycling will require further stratigraphic correlation supported with precise chronologies and paleolatitude reconstructions.

A Post-Genomic View of the Ecophysiology, Catabolism and Biotechnological Relevance of Sulphate-Reducing Prokaryotes
Ralf Rabus,Sofia S. Venceslau,Lars Wöhlbrand,Gerrit Voordouw,Judy D. Wall,Inês A. C. Pereira +5 more
TL;DR: The wealth of publications in this period is a testimony to the large environmental, biogeochemical and technological relevance of these organisms and how much the field has progressed in these years, although many important questions and applications remain to be explored.

Anomalous sulphur isotopes in plume lavas reveal deep mantle storage of Archaean crust
Rita A. Cabral,Matthew G. Jackson,Estelle Rose-Koga,Kenneth T. Koga,Martin J. Whitehouse,Martin J. Whitehouse,Michael A. Antonelli,James Farquhar,James M.D. Day,Erik H. Hauri +9 more
TL;DR: Anomalous sulphur isotope signatures indicating mass-independent fractionation (MIF) in olivine-hosted sulphides from 20-million-year-old ocean island basalts from Mangaia, Cook Islands (Polynesia), which have been suggested to sample recycled oceanic crust, suggest that sulphur was subducted into the mantle before 2.45 billion years ago and recycled into theantle source of Mangaia lavas.

Isotopic evolution of the biogeochemical carbon cycle during the Proterozoic Eon
TL;DR: Time-related changes in the Proterozoic sedimentary isotopic record of organic carbon and carbonates are consistent with the following: (1) an increase in the oxidation state of the environment, (2) a transition towards microbial populations dominated by producers and utilizers of O 2 and SO 4 2−, and (3) a relatively minor increase in organic δ 13 C during postdepositional thermal alteration as discussed by the authors.

Early evolution of atmospheric oxygen from multiple-sulfur and carbon isotope records of the 2.9 Ga Mozaan Group of the Pongola Supergroup, Southern Africa
TL;DR: In this paper, multiple-sulfur isotope mass-independent fractionation (S-MIF) is used to provide important constraints on the evolution of the early Earth's atmosphere and its impact on early life.

Fate of elemental sulfur in an intertidal sediment
Donald E. Canfield,Bo Thamdrup +1 more
TL;DR: The heterotrophic bacterial community was completely unaffected by an active metabolism conducting elemental sulfur disproportionation, and rates of sulfate reduction were identical in the elemental sulfur amended sediment, and in control sediment with no added sulfur.

Carbon and sulfur isotope abundances in Archean iron-formations and early Precambrian life
TL;DR: The results strongly indicate isotopic fractionation in the biological reduction of sulfate under anaerobic conditions from a restricted reservoir at low sulfate concentrations in the Archean basin this paper.

Effect of Low Sulfate Concentrations on Lactate Oxidation and Isotope Fractionation during Sulfate Reduction by Archaeoglobus fulgidus Strain Z
TL;DR: It is suggested that the cell channels more energy for sulfate uptake at sulfate concentrations below 300 to 400 μM than it does at higher concentrations, which could explain the shift in the metabolic pathway and the reduced growth yield and isotope fractionation at low sulfate levels.
