  1. The data represent the diameters (in millimeters) of the clear zones. Data shown are the means ± standard errors of at least triplicate experiments. The diameter of the disk is 6 mm, and each disk contained 10 μL of H2O2 (3%), cumene hydroperoxide (3% in DMSO), or menadione sodium bisulfite (90 mM in H2O).
