The antimicrobial activities of L. fermentum BT 8219 on test pathogens were evaluated by the disc diffusion assay in which discs impregnated with 20 μL L. fermentum BT 8219 culture were placed on agar seeded with the test pathogens. The diameter of the area of clearing surrounding the disc, referred to as the zone of inhibition, was used as an indirect indicator of the inhibition ability of L. fermentum BT 8219, i.e., the larger the diameter of zone of inhibition, the greater the inhibition
