Sampling before disinfection: the nutrient agar culture medium is placed at different positions of the closed space, and the cover of the culture dish is opened and placed for 5 minutes during the experiment. The cover was closed and the cells were incubated at 37 ℃ for 24 hours.
Sampling after disinfection: the fumigants of example 1 and comparative example 1 were used to fumigate with smoke for 4h, respectively, and then samples were taken after disinfection. The method of sampling after sterilization is the same as the method of sampling before sterilization, and sampling is performed at the same sampling point. The cover was closed and the cells were incubated at 37 ℃ for 24 hours.
The ratio of the two methods before and after sterilization is shown in fig. 1-4. The sterilization rate is calculated according to the following formula:
the sterilization rate is [ (number of bacteria sampled before sterilization-number of bacteria sampled after sterilization) ÷ number of bacteria sampled before sterilization ] × 100%.
The calculation results are shown in the following table:
TABLE 1 space fumigation and sterilization effect
| Sterilization rate by positioning sampling method | Sterilization rate by air sedimentation | |
| Example 1 | 100％ | 99％ |
| Comparative example 1 | 70％ | 80％ |
