Other media may be used if they've very similar growth-endorsing and inhibitory properties.

You might set up a turbidimetric calibration curve or use Yet another ideal method and Then you certainly should be able to get an estimate of the concentration within your inoculum.

five. Is it required to test the growth promotion on all been given batches or does it serve only for microbiological validation?

The non-selective agar is necessary to determine the CFU focus on the inoculum. The brand new batch of liquid media is appropriate if:

“Liquid media are suitable if Obviously obvious growth on the microorganisms corresponding to that Earlier received by using a previously tested and accredited batch of medium occurs.” To determine if a whole new batch of liquid media is appropriate, test in parallel the new batch of media, the previously permitted batch of media, and non-selective agar.
