Web3 Mar 2024 · Introduction. The oxidation of inorganic sulfur compounds by bacteria is a major part of the biogeochemical sulfur cycle. This metabolic process is exploited industrially in the bio-mining of metals [] and in cleaning fossil fuel emissions [].Oxidation of sulfur species provides the bacteria with reductant for use either in carbon dioxide … WebThe APS-sulfite redox couple has a E 0' of -60 mV, which allows APS to be reduced by either NADH or reduced ferrodoxin using the enzyme adenylyl-sulfate reductase (Apr), which requires the input of 2 electrons. In the final step, sulfite is reduced by the dissimilatory sulfite reductase (Dsr) to form sulfide, requiring the input of 6 electrons.
WebZero-valent sulfur is a key intermediate in the microbial oxidation of sulfide to sulfate. Many sulfide-oxidizing bacteria produce and store large amounts of sulfur intra- or extracellularly. It is still not understood how the stored sulfur is metabolized, as the most stable form of S(0) under standard biological conditions, orthorhombic α-sulfur, is most likely …
