SO2 emission may cause acid rain leading to environmental pollution and living-life threats. Sulfite reduction as the most important step during biological fume gas desulfurization and sulfur resources cyclic utilization has been concerned widely. Conditions of low pH, carbon desire, and temperature were investigated in this paper to reveal the characteristics of sulfite reduction by such a sort of SRB. The results show that such a sort of SRB is much sensitive to the acidic condition and could be effective to reduce sulfite within 4 days. At least C/S should reach the value 0.275 of carbon resource (calculated as COD) to keep sulfite reduced efficiently. Sulfite could be reduced at room temperature by the SRB with only 3 days delay than at 35 ℃. It cloud apply some preliminary study for biological fume gas desulfurization and recycling of sulfur resources.
