(A) The vapor phase agar diffusion experimental device. (B) MRSA treated with 500 μg phenolic EO compounds was examined by vapor phase agar diffusion tests. (C) The vapors from 500 μg phenolic EO compounds were tested by vapor phase agar diffusion. The liquid and vapor phases of (D) hinokitiol, (E) carvacrol, and (F) thymol showed different antibacterial activities after incubation at different temperatures. *P < 0.05, compared with 4°C in each curve. Dotted line, the 0.6 cm diameter of the filter disc.
