- Details on sampling:
- Sampling method:
Muller Hinton agar medium in culture dishes (35*10mm) was used for the measurement of MIC. Various concentrations of fragrance materials were prepared in ethyl alcohol or DMSO depending on the solubility of the materials. The bacteria tested were pre-propagated with sensitivity test broth of NISSUI using shaking culture. The incubated mediums were diluted by 0.75% physiological saline to the microbial concentration of 106CFU/ml. In the Muller Hinton agar medium containing fragrance material, 0.1ml of diluted culture solution was inoculated. MIC was determined as the concentration where no growth was observed after 24hrs at 37°C. - Vehicle:
