M-PA AGAR BASE

The MPN (Most Probable Number) technique results in satisfactory recovery levels of Pseudomonas aeruginosa, but is not usable for the testing of large-volumes water samples and they also lack precision for the recovery of Pseudomonas aeruginosa. Levin and Cabelli devised M-PA Agar as a selective membrane filter medium for Pseudomonas aeruginosa.
Many of the filter media used for the recovery of P.aeruginosa lack specificity and are of limited value when a large heterogeneous microbial flora is present in the water samples. The original medium was modified by raising the pH and altering the content or concentration of ingredients. This media is included in part 914 C, Membrane Filter Technique for P.aeruginosa (Tentative) in the 16th / 19th Edition of Standard Methods for the Examination of Water and Waste water.
