Purpose and Goals
- Evaluate and compare the antifungal activity of textiles in laboratory-controlled testing.
Testing
- This testing will be performed per the International Antimicrobial Council’s modification to the American Association of Textile Chemists and Colorists’ Standard Test AATCC TM30-IV.
- Sections (dimensions to be determined) of the test material will be inoculated with a liquid fungal suspension. The inoculated sections will be incubated inside sterile Petri dishes for the specified time-point in a humidified chamber. After incubation, the fungal growth on each section will be assessed as a percentage of the material’s surface area.
- Each test will include only one fungal strain — Aspergillus niger, a black fungus.
- The inoculum solution for this test will include nutrient broth — Sabouraud Dextrose broth — and a wetting agent — Triton X-100 (0.05%).
- Testing will include 24 total data points:
- 2 materials: 1 test material and 1 in-house negative control.
- Note: Please provide at least 1,500 cm2 of each material per time-point.
- 2 time-points: 0 and 48 hours.
- 3 replicates sections of each test material at each test condition
- 2 independent tests
- 2 materials: 1 test material and 1 in-house negative control.
- Note: Optional GLP services are available for an additional 25% fee.
Data Analysis
- In-house control results will be used to verify test validity.
- Data will be calculated to determine the percent fungal growth on each sample.
Typical Turn Around Time
- 2-4 weeks following receipt of the test materials
