Figure 7. Pyoverdine activity assay.

Figure 7

(a) Purified pyoverdine was loaded into the hole in CAS agar and incubated overnight at 28 °C. (b) Inhibitory concentration (IC50) and (c) lethal dose (LC50) of pyoverdine against Xoo were assayed by measuring absorbance at 600 nm and applying CFU, respectively. (d) Different concentrations of iron (150, 300, 600, 1000 μM FeCl3) were applied to antagonistic agar plates. (e) Cell growth of P. taiwanensis was detected in 1/2 TSB growth medium with 150, 300, 600 or 1000 μM FeCl3 or without FeCl3.
