Acid tolerance of an acid mine drainage bioremediation system based on biological sulfate reduction.
The acid tolerance response of an AMD bioremediation system based on sulfate reduction was investigated. Efficient sulfate reduction was observed with a maximum sulfate reduction rate of 12.3±0.8 mg L(-1) d(-1) and easily available organic carbon was released during high acid treatment with an initial pH of 2.0. The rapid increase in sulfate reduction was observed when the extreme acid treatmen...
متن کاملBioremediation by Sulfate Reducing Bacteria of Acid Mine Drainage
Mining activity produces metal sulfide wastes particularly pyrite which remain in the mine long after operations cease. When water percolates through a mine where oxygen is present, a series of chemical reactions occur which produce extremely low pH and high concentrations of toxic sulfate and metal ions. This toxic leachate can cause severe aquatic habitat degradation downstream of the mine. T...

Effect of the substrate as electron donor during the microbial sulfate reduction and its possible applications in the biological treatment of acid mine drainage
The uncontrolled release of acid mine drainage (AMD) characterized by elevated concentrations of dissolved metals, high levels of sulfate ions and low pH values threatens the quality of water resources nearby mining areas worldwide. The development of novel technologies based on the precipitation of metals as metal sulfides catalyzed by sulfate reducing bacteria constitute an important method f...
متن کاملBioremediation for Acid Mine Drainage: Organic
Biological sulfate reduction has been slowly replacing chemical unit processes to treat acid mine drainage (AMD). Bioremediations for AMD treatment are favored due to their low capital and maintenance cost. This paper describes the available AMD treatment, current SRB commercialization such as THIOPAQ® and BioSulphide® technologies, and also the factors and limitations faced. THIOPAQ® and BioSu...
