. Biological treatment with sulfate-reducing bacteria (SRB) has been considered as the most promising alternative for acid mine drainage (AMD) pollution control. Here we reported some characteristics of SRB, which was isolated from sulfate rich and low pH waste water. It was a sulfate-tolerant bacterium. In the neutral postgate’s C medium at the inoculation ratio of 1:10, and in low concentration of sulfate waster when C/S ratios was about 2.0, the sulfate removal ratio could reach more than 80%. As the sulfate concentration increased, the absolute amount of sulfate removal also increased, but its removal ratio decreased. The characteristics would provide some information for the researchers to study this sort of bacteria.
