英文摘要The utilization and speciation transformation of alpha-S-8 and mu-S by the typical mesophilic acidophilic strain Acidithiobacillus ferrooxidans ATCC 23270 were investigated. A. ferrooxidans cells first acclimated to the energy source alpha-S-8 or mu-S, respectively. The results of cell growth and sulfur oxidation behavior showed that the strain grown on alpha-S-8 entered slowly (about 1 d later) into the exponential phase, while grew faster in the exponential phase and attained higher maximal cell density and lower pH value than that on mu-S. After bio-corrosion, both of the two sulfur samples were evidently eroded and modified by A. ferrooxidans cells. After growth of A. ferrooxidans, the surface composition of amorphous mu-S became 63.1% mu-S and 36.9% alpha-S-8, and that of orthorhombic alpha-S-8 became 68.3% alpha-S-8 and 31.7% mu-S, while the surface compositions of alpha-S-8 and mu-S in sterile experiment were not changed, indicating that these two elemental sulfur species can be interconverted by A. ferrooxidans.
