PolyP levels of exponential phase cells exposed to copper. Cells of the indicated strains grown in MT (black line) or MT + P (grey line) for 6 h were exposed with increase copper concentrations for 1 h. After incubation, polyP was quantified as described in Methods. Data are expressed as average ± SD of five independent experiments.
