The acidophilic iron and sulfur oxidizing bacteria were isolatedfrom black water ecosystem, an 'extreme' ecosystemaffected indirect or directly by peat land Isolation and selection were done on minimal media (liquid and solid). All selectedstrain of bacteria (BB 179, OM 349, AH 41, TB 23, TB 27, TP 3, NN 323, and SI 188) were identified as Thiohacillusferrooxidans. Biooxidation and bio-leaching tests were accomplished using the isolated bacteria. The results showed thecapability of the isolated bacteria to oxidize ferrous-salt and to leach the low qualities of sulfide ores.
