Table 2: Inhibition of Pseudomonas aeruginosa SG81 after application of argon (Ar) or helium (He) alone, Ar or He admixed with 0.1%, 0.5% or 1% O2, and air plasma for 10–120 s treatment time in an opened or closed system. The diameter of inhibition zone (IZ) was measured in mm, the overall reduction (OR) was calculated as reduction rate of colonies in log10 (lg). No entry if no effect (NE) was observable or was not evaluable.
