It is a general purpose. Concentrated agar upto 3 more prevents swarming of Proteus species as well as Clostridium tetani. Nutrient agar is used to cultivate a variety of microorganisms.

β-Hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony. The presence of sodium chloride in nutrient agar maintains a salt concentration in the medium that is similar to the cytoplasm of the microorganisms. Composition Preparation and Uses 05 Peptone.

When the concentration of agar is reduced to 02-05gms100mL semi-solid agar is obtained which is ideal for motile organisms to spread. Nutrient agar and nutrient broth from Oxoid share almost the same medium compositionThe main difference between them is that nutrient agar contains a solidifying agent agar powder that causes the medium to solidify in room temperature whereas nutrient broth remains in liquid form. Preparation of blood agar.

It is highly valuable to microbiologists although it provides no nutrient. This relatively simple formulation provides the nutrients necessary for the replication of a large number of non-fastidious microorganisms. Water is essential ingredient for the growth and reproduction of organisms and also serves as a transport medium for the agars various substances.

The performance of the media should be checked with the help of stable typical control cultures. It is the water-soluble substances which aid in bacterial growth such as vitamins. In addition to these nutrients some vitamins and some trace ingredients necessary for the growth of bacteria are also added.

Nutrient agar is popular because it can grow a variety of types of bacteria and fungi and contains many nutrients needed for the bacterial growth. BAPs are enriched differential media used to isolate fastidious organisms and detect hemolytic activity. It is an enzymatic digest of animal protein.
