Affirm any suspect colonial progress on a number of in the media as Pseudomonas aeruginosa through the oxidase test. On the colonial expansion area or transfer colonies to strips or disks of filter paper that Beforehand has become impregnated with N,N-dimethyl-p-phenylenediamine dihydrochloride: if there's no enhancement of a pink colour, switching to purple, the specimen fulfills the necessities with the test with the absence of Pseudomonas aeruginosa.
