  6. Dear Rupesh,

    Please look into USP chapters for any method Suitability test for MLT, GPT and sterility. It's not only Pseudomonas aeruginosa , but a list of other organisms as well which is representative of gram positive and negative, aerobic and anaerobic, yeasts and mould.

    Another reason is that these are the list or representative of Specified organisms which should not be present in an pharmaceutical substance or product.

    1. Dear Friend, exposing plates in dynamic pass box under UV light is not a good idea because you'll not get actual results as UV light is bactericidal.So, either you do it in UV off condition or just perform volumetric air sampling and surface monitoring in dynamic pass box.
