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 would not existing a problem. Having said that, for non-sealed bottles or flasks of media, non-sterile air has led towards the contamination of media. Moreover, autoclaving below the expected time will also permit media related contaminants to develop and here lead to a Bogus beneficial end result. These complications may be more common in laboratories having a significant workload.
