Description of Test

  • A test organism is inoculated onto a test carpet (circular 48 mm sample) and the number of organisms present in the sample is determined.
  • After incubation, bacteria are removed from the carpet material by shaking in a known volume of extraction buffer.
  • The number of bacteria removed from the carpet material is determined by the plate count method.
  • This value is compared to the counts determined at time zero to calculate the percentage reduction by the test material.
