In membrane permeability experiment, the mean fluorescence intensity of cells treated with 200 mg l−1 carvacrol or thymol were lower than nonexposed cells. The ratio of red to green fluorescence intensity of DiOC2(3) reflected the change of membrane potential. Carvacrol and thymol at 200 mg l−1 caused the ratio of red/green decreasing from 0·42 of control to 0·08 and 0·07, respectively.
