摘要：

Two sulfur-oxidizing Thiobacillus species, T. thiooxidans ATCC 55127 and T. thioparus ATCC 55128, were isolated by enrichment from anaerobically digested sewage sludge. Under aerobic conditions, the mixed inoculum of the Thiobacillus species decreased pH of the anaerobic sludge containing sulfur from 7.8 to 2.0 in 40 h. The pH drop was achieved in two steps by the Thiobacillus species. In the first step, T. thioparus decreased the pH to a level which favored the sulfur-oxidizing activity of T. thioxidans. In the second step, T. thiooxidans decreased the pH below 2.0, at which Zn and Cu were completely solubilized within 40 and 60 h, respectively.
