for not lower than a few times. Analyze the streaked surfaces underneath UV gentle. Analyze the plates to find out whether or not colonies obtaining the characteristics detailed in Desk three are current. Affirm any suspect colonial growth on a number of from the media as here Pseudomonas aeruginosa by means of the oxidase test. On the colonial development location or transfer colonies to strips or disks of filter paper that previously has been impregnated with N,N-dimethyl-p-phenylenediamine dihydrochloride: if there's no improvement of the pink color, altering to purple, the specimen meets the necessities of your test to the absence of Pseudomonas aeruginosa.
Subculture Each and every on the cultures on a pre incubated plate of Violet purple bile glucose agar to get selective isolation.
