Based on the cleanroom classification, there can be very stringent demands on the outcome of environmental monitoring.
You ought to utilize the strains that are cited generally speaking Chapter or equivalent strains from other culture collections. Such as, if Pseudomonas aeruginosa ATCC 9027 is indicated, you must use this pressure or strains from other culture collections boasting equivalence to ATCC 9027. Other strains like ATCC 14149 are certainly not appropriate.
