Principle
Tryptone soya broth is composed of tryptone, soy peptone, dextrose, sodium chloride, and dipotassium phosphate. Tryptone and soy peptone provide nitrogen and other essential nutrients. Dextrose is a carbon source and serves as an energy source for optimum growth. Sodium chloride maintains osmotic balance, while di-potassium phosphate is a buffering agent. It is a general-purpose medium used for the cultivation of fastidious and non-fastidious organisms.
