Principles: 
The nutritionally rich base of Beef heart and Calf brain infusions and Peptone mixture provide nitrogen, vitamins, minerals and amino acids essential for growth of a variety of microorganisms. Dextrose is the carbon energy source and Sodium chloride maintains the osmotic balance. Disodium phosphate helps in maintaining the buffering action of the medium. Brain Heart Infusion Broth (BHI Medium) is very versatile and supports the growth of many fastidious organisms. With the addition of 0.1% agar, the medium is used for the cultivation of anaerobes. Adding 0.1% agar reduces the flow of oxygen convection currents and encourages the development of anaerobes and microorganisms.
