Seventy bacterial isolates were recovered from different rusted iron materials using modified NP glucose, 9K and sulfur oxidizing media. Thirty four isolates were selected after primary screening on the basis of their growth in modified NP glucose medium. Out of 34 isolates 5 belonged to the genus Kurthia, 6 Thiobacillus, 16 Bacillus and remaining 7 were Acidiphilium, Oscillospira, Sulfobacillus, Alicyclobacillus, Neisseria, Pseudomonas and Rahnella. One of the isolated organisms, Bacillus megaterium (F16/2), was found to be thermophilic. The organisms showed better growth in presence of iron salts like ferrous sulfate, ferric sulfate and ammonium ferric citrate. Five isolates were found to transform ferrous (Fe2+) to ferric (Fe3+) of which Bacillus subtilis (F8) was most efficient. A good number of bacteria were associated with oxidation of iron.

Sewage contains high concentration of sulfate and contaminates ground water supply. The production process in the factory produced sewage containing high amount of sulfur such as sulphide and sulphate. Sulfur bacteria, which are capable of oxidizing, reducing or partially oxidizing inorganic sulfur compounds such as Thiomicrospira, Thiothrix, Desulforomonas, Achromatium, and a group of Thiobacillus. Utilization of sulfur bacteria has done in attemp to find sewage bioremediation agents as well as to promote soil fertility. Isolation and characterization were carried out by growing the bacteria in the starkey selective medium, including pH reduction test, morphology, physiology and biochemical characterization. It has been observed that out of 2 isolates from different sources of samples (rubber and paper sewage), only one isolates related to sulfur-oxidizing bacterium (SOB) while  the isolates AE01 related to true sulfur-oxidizing bacterium in genus Thiobacillus.

An acidophilic, rod-shaped, sulfur-oxidizing bacterium was isolated from extremely acidic soil adjacent to a sulfur stockpile at Fox Creek, Alta. This isolate was found to grow only autotrophically by oxidizing S° and reduced inorganic sulfur compounds (S2O32− and S4O62−), placing it in the genus Thiobacillus. Aerobic growth was observed over a pH range of 2.0 to 4.5 with optimum growth at 3.5 to 4.0. Analysis of its DNA revealed a mol% G + C content of 61.5. Ultrastructural studies showed that the isolate possessed a tuft of polar flagella. A glycocalyx was observed only after the antiserum stabilization procedure, which showed it extending outwards from the outer membrane of the bacterial cell envelope. Cleavage planes of this cell showed a typical Gram-negative cell wall. The cytoplasm contained two types of inclusion bodies, carboxysomes and a single large membrane-bound sulfur granule. This isolate had morphological and physiological characteristics which were not totally comparable with other known acidiophilic thiobacilli demonstrating this bacterium to be a new Thiobacillus sp. named T.albertis.
