Inspect the autoclaves used for the sterilization of media. Autoclaves could absence the chance to displace steam with sterile filtered air. For sealed bottles of media, This could not existing an issue. On the other hand, for non-sealed bottles or flasks of media, non-sterile air has led on the contamination of media.
