| Abstract: | Objective] The new approach of integrated development and utilization of mugwort plant was explored through the research on the extract from mugwort and the fumigation of mugwort on the inhibition to 3 microorganisms: E.coli,B.subtilis and Penicillium.Method] The inhibitory role of the extract with various concentrations from mugwort and the fumigation of mugwort to 3 microorganisms was tested with filter paper diffusion method.Results] There was obvious inhibitory effect of the extract from mugwort and the fumigation of mugwort to E.coli,B.subtilis and Penicillium.The order of the inhibitory effect of the treatments to 3 microorganisms was E.coli > B.subtilis> Penicillium.The minimum concentration of the extract from mugwort inhibiting the E.coli,B.subtilis and Penicillium was 0.033 3,0.028 6 and 0.040 0 g/ml,respectively.Conclusion] It was confirmed the mugwort had inhibitory effect on bacteria and the inhibitory effect of the mugwort on bacteria was stronger than on mold. |
