Inorganic Polyphosphate, Exopolyphosphatase, and Pho84-Like Transporters May Be Involved in Copper Resistance in Metallosphaera sedula DSM 5348T

Figure 1

Effect of copper ions in the growth and PolyP levels of M. sedula DSM 5348T. Growth curves (a) and polyP levels (b) were determined at the indicated copper concentrations added upon inoculation. Cells previously grown up to the late exponential phase were shifted to grow at 8 mM CuSO4 at time 0, and polyP levels were immediately determined thereafter at the indicated times after the shift (c).
