To lay down a procedure for evaluating the growth promotion and inhibition Qualities of media utilized for Microbiological testing.
Utilizing aseptic methods, inoculate the microbial strains onto the organized society media. Follow the Guidelines delivered while in the SOP to guarantee suitable handling and distribution in the strains. Listen to the precise portions and areas for inoculation as laid out in the SOP.
The TSB tubes are incubated under suitable situations, and right after incubation, the tubes displaying growth are counted. The bacterial count in the original sample can then be calculated dependant on the dilution things.
Following a specified incubation time period, observe the plates for growth and count the colonies attained in Each individual plate and report the outcome in Annexure-II.

Many thanks for The entire factor!
The micro-organisms are to get added to your diluted/suspended product or service at the end of the planning (usually a one in 10 dilution is prepared) or following the neutralization (in the last portion with the rinsing fluid in the case of filtration or at the same time with the preparation in/around the Petri dish in the case with the plate count method) if inhibition of growth with the sample can't if not be avoided. The 100 CFU refers to the inoculum (e.g., what's going to be to the filter or on the plate).
Negative Command To verify testing situations, a unfavorable Command is performed utilizing the preferred diluent instead of the test planning. There needs to be no growth of microorganisms.
