Sulfor oxides

Sulfor oxidizing bacteria oxidize sulfide and sulfite to sulfate. The decrease of oxygen [94,95] as well as the alteration of pH [96] can be used as indicators of these reactions. With a Thiobacillus thioparus-containing sensor, a detected limit of 4 pmol/1 sulfite is reached [94]. The detection limit of a sensor with Thiobacillus thiooxydans for sulfide is 0.02 mmol/1 only [95].

Metabolic oxidation reactions may occur to the side chains of sulfor-containing residues, similar to that observed for in vitro chemical instability. Methionine can be oxidized to the sulfoxide, whereas metabolic oxidation of cysteine residues forms a disulfide. Metabolic reductive cleavage of disulfide bridges in proteins may occur, yielding free sulfhydryl groups.

The liquid from the centrifuge flows into a clarifier from which settled particles are returned to the crystallizer, and clarified liquor (containing 0.7 to 1.0% sulforic acid) is returned to the absorber/oxidizer circuit The flow rate of the return stream is approximately 500 gpm. A small amount of the dilute acid is continuously purged from the system to prevent build-up of chlorides that could cause corrosion of stainless steel equipment. A chloride limit of 200 ppm has been specifred for the plant Hie catalyst, iron sulfate, is not a major...
