Subsequent the Directions while in the SOP, prepare the culture media wanted to the test. This might involve sterilizing the media, introducing appropriate nutrients, and altering pH degrees. It is important to stick to the required procedures exactly to be certain correct and dependable test success.

The colonies are similar in physical appearance and indication reactions to People previously received which has a Formerly tested and approved batch of medium.
For quantitative methods for example growth promotion testing, a certified reference product which has a quantitative assets worth, such as cfu, would even further enrich the ability to obtain comparable outcomes as per pharmacopeia requirements.
As an example, in rooms for instance ISO five and six, the cfu counts allowable are exceptionally low and should be managed quite closely. In USP Microbiological Command and Monitoring of Aseptic Processing Environments, it states that prompt Original contamination Restoration prices for aseptic environments in ISO 5 and ISO 6 rooms ought to only clearly show contamination on top of things plates
dimaksudkan untuk kontrol positif apakah media benar-benar dapat ditumbuhi bakteri sesuai jumlah bakteri yang ditanam pada media tersebut, apabila dari media yang ditanam bakteri yang jumlahnya misalkan seventy five cfu dan ternyata jumlah bakteri yang tumbuh kurang dari fifty% dari jumlah bakteri yang ditanam dapat disimpulkan bahwa pengujian jumlah bakteri dan jamur pada sampel produk tidak legitimate karena media tidak dapat menumbuhkan bakteri sebagaimana mestinya.
