[Identification and distribution of sulfur in Thiobacillus ferrooxidans cells]

Sulfur localization was studied in Thiobacillus ferrooxidans cells grown in the medium 9K containing elemental sulfur. When sulfur is oxidized to sulfuric acid, it is located on the surface of the cell wall and within the cell wall at different levels of the periplasmic space, as well as in large spherical structures arranged at the poles or in the center of the cell. The authors discuss the mechanism of sulfur transport and distribution in T. ferrooxidans cells when sulfur is oxidized to sulfuric acid.
