A comparison of two chemistry and aerosol schemes on the regional scale and the resulting impact on radiative properties and liquid- and ice-phase aerosol–cloud interactions by F. Glassmeier, F. Glassmeier, F. Glassmeier, A. Possner, A. Possner, B. Vogel, H. Vogel, U. Lohmann

“…We consider the aerosol module MADE (Modal Aerosol Dynamics model for Europe) in combination with full gas-phase chemistry and the aerosol module M7 in combination with a constant-oxidant-field-based sulfur cycle. For a Saharan dust outbreak reaching Europe, modeled aerosol populations are more sensitive to structural differences between the schemes, in particular the consideration of aqueous-phase sulfate production, the selection of aerosol species and modes, and modal composition, than to parametric choices like modal standard deviation and the parameterization of aerosol dynamics. …”

Multiple Sulfur Isotope Evidence for Bacterial Sulfate Reduction and Sulfate Disproportionation Operated in Mesoarchaean Rocks of the Karelian Craton by Sergey V. Vysotskiy, Tatyana A. Velivetskaya, Aleksandr V. Ignatiev, Aleksandr I. Slabunov, Anna V. Aseeva

“…Sulfur isotope in sulfides from the Paleoarchean and the Neoarchean sedimentary rocks evidence microbial sulfur metabolism in Archean sulfur cycle. However, sulfur metabolism for the Mesoarchean interval is less obvious since evidence for a large range in sulfur isotope values has not yet been observed in Mesoarchean samples. …”

Mission to planet Earth: the first two billion years by Stüeken, EE, Som, SM, Claire, M, Rugheimer, S, Sherf, M, Sproß, L, Tosi, N, Ueno, Y, Lammer, H

“…Crucial aspects included: (1) the redox state and volatile content of Earth’s building blocks, which determined the longevity of the magma ocean and its ability to degas H2O and other greenhouse gases, in particular CO2, allowing the condensation of a water ocean; (2) the chemical properties of the resulting degassed mantle, including oxygen fugacity, which would have not only affected its physical properties and thus its ability to recycle volatiles and nutrients via plate tectonics, but also contributed to the timescale of atmospheric oxygenation; (3) the emergence of life, in particular the origin of autotrophy, biological N2 fixation, and oxygenic photosynthesis, which accelerated sluggish abiotic processes of transferring some volatiles back into the lithosphere; (4) strong stellar UV radiation on the early Earth, which may have eroded significant amounts of atmospheric volatiles, depending on atmospheric CO2/N2 ratios and thus impacted the redox state of the mantle as well as the timing of life’s origin; and (5) evidence of strong photochemical effects on Earth’s sulfur cycle, preserved in the form of mass-independent sulfur isotope fractionation, and potentially linked to fractionation in organic carbon isotopes. …”

Enhanced metabolic versatility of planktonic sulfur-oxidizing γ-proteobacteria in an oxygen-deficient coastal ecosystem by Alejandro A. Murillo, Salvador eRamírez-Flandes, Edward F. DeLong, Osvaldo eUlloa

“…Finally, members of ESP-GSO cluster also have the genetic potential for reducing nitrate to ammonium based on the nirBD genes, and may therefore facilitate a tighter coupling of the nitrogen and sulfur cycles in oxygen-deficient waters.…”

Transcriptomic analysis of the response of Acropora millepora to hypo-osmotic stress provides insights into DMSP biosynthesis by corals by Catalina Aguilar, Jean-Baptiste Raina, Cherie A. Motti, Sylvain Fôret, David C. Hayward, Bruno Lapeyre, David G. Bourne, David J. Miller

“…Abstract Background Dimethylsulfoniopropionate (DMSP) is a small sulphur compound which is produced in prodigious amounts in the oceans and plays a pivotal role in the marine sulfur cycle. Until recently, DMSP was believed to be synthesized exclusively by photosynthetic organisms; however we now know that corals and specific bacteria can also produce this compound. …”

Periodicities in the emplacement of large igneous provinces through the Phanerozoic: Relations to ocean chemistry and marine biodiversity evolution by Andreas Prokoph, Hafida El Bilali, Richard Ernst

“…A shift from the 64.5 Ma to a weaker ∼28–35 Ma LIP cyclicity during the Jurassic contributes together with probably independent changes in the marine sulfur cycle to less ocean anoxia, and a general stabilization of ocean chemistry and increasing marine biodiversity throughout the last ∼135 Ma. …”

Screening of metagenomic and genomic libraries reveals three classes of bacterial enzymes that overcome the toxicity of acrylate. by Andrew R J Curson, Oliver J Burns, Sonja Voget, Rolf Daniel, Jonathan D Todd, Kathryn McInnis, Margaret Wexler, Andrew W B Johnston

“…Acrylate is produced in significant quantities through the microbial cleavage of the highly abundant marine osmoprotectant dimethylsulfoniopropionate, an important process in the marine sulfur cycle. Acrylate can inhibit bacterial growth, likely through its conversion to the highly toxic molecule acrylyl-CoA. …”

Characterization of microbial-induced concrete corrosion by combining morphology observation and fluorescence staining by Junfeng Wang, Shouyi Yin, Liulei Lu, Jingya Zhou, Qionglin Fu

“…The results demonstrate that compared with the freshwater group, the seawater group with a high salt content is more favorable for biofilm adhesion to the concrete surface and induces more serious corrosion owing to the biological sulfur cycle reaction. The biological sulfuric acid produced by microbial metabolism corrodes concrete to produce gypsum and other corrosion products. …”
