The MLT tests are often performed on non-sterile pharmaceutical, healthcare and cosmetic products which can range between raw elements to completed products.
for not under 3 times. Take a look at the streaked surfaces less than UV light. Examine the plates to determine no matter if colonies owning the attributes shown in Table 3 are current. Affirm any suspect colonial advancement on one or more on the media as Pseudomonas aeruginosa by the use of the oxidase test. On the colonial advancement location or transfer colonies to strips or disks of filter paper that Beforehand continues to be impregnated with N,N-dimethyl-p-phenylenediamine dihydrochloride: if there isn't a development of the pink color, switching to purple, the specimen satisfies the necessities in the test to the absence of Pseudomonas aeruginosa.
Prepare sample by dissolving 10g of product or service less than test in 100 ml of Soybean Casein digest medium.
