Due to the rapid kinetics involved in sulfide oxidation by dissolved oxygen, some sulfide-oxidizing bacteria are in continuous competition with the chemical oxidation mechanism. The latter authors suggest the Acidithiobacillus thiooxidans, formerly known as Thiobacillus thiooxidans, is an acidophilic bacterium that oxidizes S 0 and thiosulfate, but not iron. Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. The isolation process was conducted on Thiobacillus agar supplemented with bromocresol green to detect the production of sulfuric acid by the isolates. H 2 S was biologically removed by T.
