Biological oxidation of ferrous iron in an air-lift bioreactor

Biological oxidation of ferrous iron is an important potential in industrial processes such as H2S removal in natural gas, leaching operation or treatment of acid mine drainage water. Owing to the fact that bio-oxidation process has high efficiency and economical benefits, it is evident that we should expand our knowledge in this case. The purpose of this paper was to treat Fe2+ ions with the usage of Thiobacillus ferrooxidans in laboratory, and after finding appropriate results, we designed an air-lift bioreactor and expanded our work to that vessel in continuous mode.
