Ну, навскидку:

...There has been no convincing scientific evidence published that would argue for the need to test Trypticase Soy media, for example, for growth promotion. However, both the Sterility Test and the Microbial Limits Tests require such testing. Given the compendial requirement to test, the first decision may reasonably be to determine the challenge organism. In addition to the compendial organisms required in the tests, addition of specific microorganisms of interest could be useful if they have been recovered from past tests (e.g. a Sterility Test contaminant or a frequent environmental monitoring isolate).
