Acidophilic bacteria play an important role in environmental and industrial processes. Chemolithotrophic and heterotrophic bacteria benefit bioleaching applications by solubilizing metals from sulfide minerals (12, 14,38).Conversely, the production of ferric iron and sulfuric acid by certain acidophilic bacteria may cause significant environmental damage by inducing acidic mine drainage and
