for not fewer than three times. Take a look at the streaked surfaces under UV mild. Look at the plates to ascertain whether or not colonies acquiring the traits shown in Table three are current. Confirm any suspect colonial development on one or more of the media as Pseudomonas aeruginosa by the use of the oxidase test. Upon the colonial progress area or transfer colonies to strips or disks of filter paper that Beforehand has actually been impregnated with N,N-dimethyl-p-phenylenediamine dihydrochloride: if there isn't any advancement of the pink colour, modifying to purple, the specimen satisfies the requirements from the test for the absence of Pseudomonas aeruginosa.
