of extremely thermophilic A. manzaensis [12] and moderately thermophilic Sulfobacillus thermosulfidooxidans [20]. Results of A. manzaensis showed that bio-corroded μ-S was composed of 92.1% α-S8 and 7.9% μ-S... acidophilic strain Acidithiobacillus ferrooxidans ATCC 23270 were investigated. A. ferrooxidans cells first acclimated to the energy source α-S8 or μ-S, respectively. The results of cell growth......
