Figure 2.Growth rates of wild-type strain s and of the PaMth1 deletion strain on synthetic PASM medium containing different amounts of CuSO4 and of hydrogen peroxide, respectively.
Pairs of strains (wild-type strain s and the PaMth1
knock-out strain) were grown on one plate and growth rates were recorded
over 3 days. Cultures of the PaMth1 deletion strain (n = 20) were
characterised by decreased growth rates compared to the wild-type strain s
(n = 20) when incubated on medium containing 40 μM (p = 6.154e-08) or
80 μM (p = 1.921e-08) CuSO4 and 0.01% (p = 1.443e-08); 0.02% (p =
1.06e-07) or 0.04% (p = 0.99) hydrogen peroxide. Plates containing hydrogen
peroxide were incubated in the dark.
