Abstract
Oxidation of elemental sulfur by Acidithiobacillus ferrooxidans
was characterized by kinetic and physiological parameters. The
bacterial cell attachment on the sulfur surface corresponded to
the Langmuir isotherm at the beginning of sulfur oxidation. A
violet-colored metabolite from the cultures was isolated and
partially characterized. The proposed chemical structure
indicated its possible role in cell adsorption onto elemental
sulfur during the cell growth. Sulfur limitation and oxidation
activity of free cells were fundamental to explain data of
sulfur biooxidation. The role of adsorbed bacteria in sulfur
solubilization was discussed.
