Growth promotion has to be tested for every new batch of medium. Growth promotion have to be checked on agar media and nutritive broth but not on diluted broth.
You could possibly create a turbidimetric calibration curve or use One more suited method and Then you definitely can get an estimate with the concentration of your respective inoculum.
Now it is possible to take advantage of the entire prospective of this template to carry out growth promotion tests:
The Peter Principle represents a big challenge in hierarchical organizations, where staff members may perhaps obtain by themselves promoted beyond their competency amount and Management is disappointed by bad perform top quality.
