For common objective agar media only, Growth Promotion Test shall be completed by inoculation method with exemption of inhibitory and indicative test.
If utilizing the Pour Plate Method, increase 0.one ml in the microorganism suspension to the sterile Petri dish. Pour molten agar above the inoculum and mix effectively by swirling the contents while in the plate. Invert and incubate the agar after it's got solidified.
