WebSulfite oxidase deficiency is characterized by severe neurologic dysfunction, dislocation of the lenses, and the accumulation and excretion of inorganic sulfite, thiosulfate, and S … WebFigure 1 shows the scheme of the sulfide oxidation system for experiments. The key to the successful biological sulfide oxidation is the O 2 level and is sometimes represented by S[2−]/O 2 ratio. Under microaeration conditions (saturation of the solution with oxygen kept at 1%), S[2−] can be efficiently converted to S[0] by SOB .
WebDec 24, 2024 · Sulfur oxidation involves the oxidation of reduced sulfur compounds such as sulfide (H 2 S), inorganic sulfur (S 0 ), and thiosulfate (S 2 O 2−3) to form sulfuric acid (H 2 SO 4 ). An example of a sulfur … WebIt did not inhibit the sulfite oxidation by cells, but inhibited any reduction of cell cytochromes by sulfur, thiosulfate, tetrathionate, and sulfite.
