是一个试验方法，请不要用翻译软件来翻译，谢谢！
The test method is described in ISO 6222.（这个检测方法是按照ISO6222描述）
In the DryDes P-test the samples were taken from a floor in a pig sti.
1 sample was taken from an untreated squaremeter floor and from 1 squarmeter floor treated by 50 gram DryDes P pr sq.m another sample was taken!
The samples were diluted in warm water mcc. to ISO 6222 and placed in Petri-bowls with agar and subrstrate at 37 degC for 48 hours!
After this curing the cells will grow.
Then the number of cells is counted.
In the Petri-bowls with sample from the untreated floor the number of grown cells is expedted to be high!
In the Petri-bowls from sample from a treated floor, the number of cells will be low!
Normally we have 3 petri bowls pr sample. <I.e. here the total number in test was 6> The difference in number of cells is the reduction in bacterias at the treated floor!
