Given below is general information pertaining to the AATCC 100Test: 


AATCC 100 antimicrobial test method is a quantitative method in which assessment of antibacterial finishes is determined on the test materials.

  1. Test bacteria are grown in liquid medium and diluted to specific bacterial concentration.
  2. The test and control swatches are inoculated with the test cultures taking care that the suspension touches only the fabric.
  3. The concentration of the bacteria used for the test is determined at the initial “zero h” and at end of contact time.
  4. At selected time points, organisms are extracted in neutralizing medium. Bacterial population is determined by dilution and plating.
  5. The log reduction or percentage reduction is calculated by using survival data from treated and un-treated test material at that specific contact time.

Microorganisms used are: Staphylococcus aureus and Klebsiella pneumoniae. Other microorganisms from our culture are available upon request. 

The method is reproducible and can be determine both bacteriostatic as well as bactericidal effect of the antimicrobial testing agent.
