Acid mine drainage (AMD) waters are highly acidic (pH < 4), contain high concentrations of sulfate and dissolved metals, and are very toxic to many living organisms. The development of technologies to treat sulfate contaminated wastewaters by using sulfate-reducing bacteria (SRB) has produced a cost-effective route to treat AMD. Notwithstanding, the SRB sensitivity to acid limits their use in AMD remediation. In the current study, acidophilic strains of SRB were isolated from an AMD followed by their molecular characterization. One SRB-culture was able to grow at pH 4.5 in Postgate C modified medium containing ethanol as carbon source, indicating that such bacterium has the potential for the bioremediation of acidic waters. Following, the strains were characterized by molecular biology techniques. The characterization was done by PCR amplification, cloning and sequencing of the genes coding for parts of the alpha and beta subunits of dissimilatory sulfite reductase (dsrAB) and hydrogenase (hyd), which encode key enzymes of the SRB energy metabolism. Phylogenetic analysis suggested a line of SRB descent from the delta-Proteobacteria among the strains identified as Desulfovibrio fructosovorans.

By experiments, separate and purify efficient sulfate—reducing bacteria (SRB), which is identified as Desulfobacter. With its treatment of acid mine drainage(AMD) containing Fe2+ and Mn2+, obtain the optimum conditions that pH=6,temperature=37,vibrating intensity=100r/min, COD/SO42- =2.Under this condition ,the removal rate of SO42-、Fe2+ and Mn2+ is 88.16%、99.37% and 59.18% respectively with the initial concentration 1411mg/L for SO42-,257mg/L for Fe2+ and 325mg/L for Mn2+.This puts a theoretical foundation for the further study.
