AATCC 147 – Antibacterial Activity Assessment of Textile Materials: Parallel Streak Method
AATCC 147, also known as Parallel Streak Method is a qualitative test method to determine the bacteriostatic activity of diffusible antimicrobial finishes on textile materials. However, this test method is not applicable for textile materials that can’t be diffused through bacterial growth medium or are impregnated with any antibacterial-neutralizing substances.
AATCC 147 test method is easy to perform and provides reliable and reproducible results. Additionally, it is helpful for expediting the screening of a large amount of samples in comparison to other commonly used quantitative standard methods like AATCC 100 and JIS L 1902.
AATCC 147 Test Method
- Molten agar media is poured into the sterile petri plates and allowed to solidify.
- A sterile loop is used to obtain the inoculum from a 24-hour-old broth and is transferred to the surface of the agar medium.
- Through the edge of the inoculated area, 5 streaks are made on the agar medium.
- Test samples (treated) of size 25 × 50 mm are placed across the 5 streaks ensuring proper contact between the antimicrobial agents and test bacteria. Meanwhile, a parallel experiment is performed with control (untreated) samples.
- All petri plates are incubated at 37 ± 2°C for 18-24 h.
- After incubation, petri plates are examined for interrupted bacterial growth along the streaks and clear zone of inhibition that occur due to the presence of the antibacterial agents.
Microbe Investigation has an exclusive facility for antimicrobial testing, which caters to the requirement of clients worldwide. We help our clients to identify the efficacy of their antimicrobial products under specified test conditions such as temperature, test organisms, incubation period, etc.
For the antibacterial testing of textile materials, we offer both qualitative (AATCC-147) and quantitative test methods (AATCC 100, JIS L 1902 & ISO 20473).
