The cellophan is stripped off and the test organisms are streaked on the sterile agar surface thereby revealed, at right angles to the first streaks. After incubation, growth of the test organisms will be interrupted in those areas in which an inhibitor has diffused through the cellophan from the first organisms. There are some limitations in the application of the method. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-1-2-168
