Web4.5 Sulfur-oxidizing bacteria. The common sulfur-oxidizing bacterium Thiobacillus thiooxidans is a chemo-lithotroph utilizing thiosulfate and sulfide as sources of energy to produce sulfuric acid. This broad family of aerobic sulfur bacteria derives energy from the oxidation of sulfide or elemental sulfur to sulfate. WebThe H 2 S combines with water to form sulfuric acid (H 2 SO 4), a strongly corrosive acid. Corrosion due to H 2 SO 4 is often referred to as sour corrosion. Since hydrogen sulfide combines easily with water, damage to stock tanks below water levels can be severe. Water with hydrogen sulfide alone does not cause disease. helper boy
