Figure 4. Analysis of hydrogen peroxide tolerance. The growth rate of wild-type, PaCatB deletion strain (ΔPaCatB) and the three independent PaCatB over-expression strains (PaCatB_OEx1-3) were investigated under oxidative stress. A Growth rates of PaCatB over-expression strains (n=8) were measured on PASM containing 0, 3, 6, 9, 12, 21, 27, 33, 39 and 45 mM hydrogen peroxide and were statistically significant for 3, 6 and 9 mM (PaCatB_OEx1-3: p<0.01), 12, 21, 27 and 33 mM (PaCatB_OEx1-3: p<0.01) and 39 mM hydrogen peroxide (PaCatB_OEx1-2: p<0.01).B Growth rates of PaCatB deletion strain (n=8) were measured on PASM containing 0, 0.375, 0.75, 1.5 and 3 mM hydrogen peroxide and were statistically significant for 0.75, 1.5 und 3 mM hydrogen peroxide (p-value: p<0.01). Error bars are ± SEM.
