PM INDICATOR AGAR (PENICILLIN IN MILK INDICATOR AGAR) (as per AOAC)

PM Indicator Agar is used for rapid detection of trace amounts of penicillin in milk where AOAC has recommended Bacillus stearothermophilus qualitative discs. PM Indicator Agar is designed according to the formula published by the 18th Annual Meeting of the National Mastitis Council. This method is a modification of the method approved by the International Dairy Federation for the qualitative detection of penicillin in milk. Originally a medium called Reductase Medium was suggested by Reid and Brewer for detecting penicillin in milk by using Bacillus subtilis. The present medium is better, faster and more reliable than that of Reid and Brewer (This medium is designed to support and demonstrate the growth and acid formation by B. stearothermophilus, which is sensitive to penicillin and b-lactam residues). To demonstrate the presence of traces of penicillin in milk; the qualitative disc method is found to be more suitable which is also recommended by AOAC.
