Nutrient media are basic media used for the cultivation of less fastidious microorganisms, but can be used for cultivating fastidious organisms by enriching with different biological fluids such as horse or sheep blood, serum, egg yolk etc.1. This relatively simple formula has been retained and is still widely used in the microbiological examination, useful in routine cultivation of microorganisms2,3. This is the most popular medium for demonstration and teaching purposes where a more prolonged survival of cultures at ambient temperature is often required without risk of overgrowth that can occur with more nutritious substrate.

User Quality Control
Check for signs of contamination and deterioration. Users of commercially prepared media may be required to perform quality control testing with at least one known organism to demonstrate growth or a positive reaction; and at least one organism to demonstrate inhibition or a negative reaction (where applicable).
