To lay down a procedure for evaluating the growth promotion and inhibition properties of media utilized for Microbiological testing.
5. Will it must be finished when the solution is tested or during the method validation or could it be achievable to get it done periodically?
Growth Promotion Testing (GPT) is so foundational to Microbiological item protection that it may be uncomplicated to overlook. Most industrial microbiologists have an understanding of the significance of GPT, but this important test is typically carried out incompletely and inconsistently.
one. Don’t count on a microorganism to improve too on selective agar as on non-selective agar (even though the non-selective agar was designed for the microorganism species)

Although the formulation often is the exact from model to brand name, they may not be created equivalent. Adjustments may should be manufactured inside the formulation to meet the maker’s specification or elements may originate from diverse sources.
Can we use streaking around the selective media under GPT test as selective media use just for qualitative Investigation? kindly support.
