N2  - A simple method that allows easy identification of rifamycin B-producing strains is described. This method involves the use of an enzyme, rifamycin oxidase, which converts inactive rifamycin B to active rifamycin S. In this method, colonies to be tested are grown in pairs. The two colonies are then transferred to two plates seeded with a sensitive strain of Staphylococcus aureus, one plate of which contains the enzyme rifamycin oxidase. All paired colonies which show a larger inhibition zone diameter on the enzyme-containing plate are identified as rifamycin B producers.
