Nutrient agar is a general medium used for a wide range of microorganisms.

Purpose:

Nutrient agar is used for less demanding microorganisms, as well as for permanent crops (general medium). The medium contains beef extract, yeast extract and peptone as a source of nitrogen. Sodium chloride guarantees osmotic balance. Agar is an agent. The addition of 10% of various biological fluids, such as blood, serum and egg yolk makes it suitable for growing the relevant demanding organisms. For example: Pseudomonas aeruginosa produces a blue-green pigment, piocyanin, which diffuses into the medium, giving a strip of characteristic color. To grow a specific bacterial culture, spread bacteria on the plate with a sterile tampon or a modified loop. Bacteria will grow and become visible within 24 - 48 hours. It is usually used in the laboratory when preparing stocks of bacterial cultures.

Peptone - 5.00 Grams / liter
