Isotopic Signatures of Sulfur Cycling Organism Physiology and Ecology
Dissimilatory S metabolisms impart large S and O isotope fractionations, which are modulated by a suite of (bio)chemical reactions and physical processes (i.e., diagenesis) and ultimately preserved in the reduced and oxidized products of sedimentary S cycling (e.g., pyrite, carbonate-associated sulfate). The multi-isotope composition of such compounds encodes valuable information about microbial activity, environmental conditions, and elemental cycles. Robust interpretation of these signals requires mechanistic understanding of both the metabolic isotope fractionation itself and the impacts of diagenesis on its ultimate preservation. Such understanding is currently limited by simplified…
