Molecular Characterization of Copper and Cadmium Resistance Determinants in the Biomining Thermoacidophilic Archaeon Sulfolobus metallicus
Figure 1
Growth of S. metallicus (a) and S. solfataricus (b) in the presence of Cd. Cells were inoculated in their respective growth media in absence of added Cd (●), or were supplemented with 0.005 mM (□), 0.01 mM (▲), 0.05 mM (◊), 0.1 mM (⚪), 0.5 mM (■), 1 mM (△), 2 mM (♦), 3 mM (×), or 5 mM (+) Cd, and cells were counted daily.
