AATCC 90 – Antibacterial Activity Assessment of Textile Materials: Agar Plate Method

1. Purpose and Scope

1.1 The objective is to qualitatively detect bacteriostatic activity on products that are treated with antimicrobials and are capable of producting a zone of inhibitation. Some test samples do not have a flat surface, therefore, this method provides the advantage of testing odd shaped and non-flat surfaces by partially embedding them into molden agar prior to solidification. This provides the intimate contact required between the test sample and the seeded agar.
