reduction of sulfate to sulfide is the step of the sulfur cycle.
what are the steps of the sulfur cycle?
reduction of sulfate to sulfide
bullet::::- mineralization of organic sulfur into inorganic forms, such as hydrogen sulfide (hs), elemental sulfur, as well as sulfide minerals.









































bullet::::- oxidation of hydrogen sulfide, sulfide, and elemental sulfur (s) to sulfate (so).









































bullet::::- reduction of sulfate to sulfide.









































bullet::::- incorporation of sulfide into organic compounds (including metal-containing derivatives).









































these are often termed as follows:









































section::::sulfur oxidation state.









































sulfur has four main oxidation states in nature, which are -2, +2, +4, and +6. the common sulfur species of each oxidation state are listed as follows:









































s: hs, fes, fes, cus









































s: native, or elemental, sulfur









































s: so
sulfur cycle
sulfur cycle









































the sulfur cycle is the collection of processes by which sulfur moves between rocks, waterways and living systems. such biogeochemical cycles are important in geology because they affect many minerals. biochemical cycles are also important for life because sulfur is an essential element, being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in microbial respiration. the global sulfur cycle involves the transformations of sulfur species through different oxidation states, which play an important role in both geological and biological processes.
