FIG. 2.
Dependence of sulfur dissolution (bioleaching) on EPS composition for cells of T. ferrooxidans. Dissolution was measured before (sterile) (A) and after (B) inoculation with EPS-deficient (1) or -containing (2) cells of iron(II) sulfate-grown bacteria by sulfate concentration in the medium (circles), heat output on the substratum (bars) and cell concentration of planktonic bacteria (asterisks). d, days.
