Prior to the availability of substantial-top quality reference elements, growth promotion testing was commonly executed by plating a serial diluted microorganism suspension on the two a different in addition to a Beforehand launched media batch to check recoveries. This method proved hard in obtaining correct success
Microbial monitoring applications for controlled environments should really evaluate the success of cleaning and sanitization techniques by and of staff that would have an effect on the bioburden of the managed surroundings. Microbial monitoring, irrespective of how sophisticated the technique may be, will not likely and need not determine and quantitate all microbial contaminants current in these controlled environments.
In the event that a batch of media would not satisfy the requirements of growth promotion testing, an investigation really should be initiated to determine the reason for the nonconformance and corrective/preventive motion plans needs to be dealt with.
