Inoculate a non-selective agar plate in parallel Using the similar suspension accustomed to inoculate the liquid media. The non-selective agar plate serves as a viability Management and will inform you the number of microorganisms were being additional to your liquid media.
Growth promotion testing of society media is a crucial part of microbiological testing in assistance of pharmaceutical good quality
After a specified incubation period, notice the tube/flask and record the observations in Annexure I.
Peptic digest of animal tissue and yeast extract serve as sources of carbon, nitrogen, vitamins and also other necessary growth nutrients.
If utilizing the Pour Plate Method, insert 0.1 ml of the microorganism suspension to a sterile Petri dish. Pour molten agar over the inoculum and blend effectively by swirling the contents within the plate. Invert and incubate the agar following it's got solidified.
