Principle
- Nutrient agar is a basic medium and commonly used for cultivation, enrichment, enumeration, prolonged maintenance, and storage of a wide variety of microbes.
- The nutrient agar is widely used as a non-selective microbial medium for routine microbiology analysis.
- Nutrient agar is prominently used for cultivation of the non-fastidious organisms.
- Nutrient agar is ideal microbial media for teaching, demonstration, and routine analysis.
- Nutrient Agar is a simple medium composed of peptone, meat extract (equivalent to beef extract), and yeast extract which provide ample amounts of the carbon and nitrogen essential and non-essential amino acids, along with the vitamins and trace minerals. Sodium chloride maintains the osmotic equilibrium of the medium. Agar is the solidifying agent.
