WebThe sulfur cycle involves eight electron oxidation/reduction reactions between the most reduced H2 S (−2) to the most oxidized (+6). It acts as either electron donor or acceptor in many bacterially mediated reactions. The oxidation states of key sulfur compounds are given in the following table: Organic. S (R–SH) −2. Sulfide. Web30 Nov 2024 · To address the role of possible cryptic sulfur cycle intermediates, that is, reduced forms of sulfur, in Experiment IV we used amendments with zero-valent sulfur (S 0) and MoO 4 2− + S 0. These amendments investigated two possibilities: S 0 as an electron acceptor for AOM, and S 0 as an intermediate supporting sulfate-dependent AOM trough …
