This is a general purpose and nutritious medium for the non-selective enrichment of non-fastidious and some fastidious organisms. Tryptone and Soy peptone are the nitrogen sources in the medium. Glucose is the carbon energy source that facilitates organism growth. Sodium chloride maintains osmotic balance; Di-potassium phosphate is a buffering agent to prevent auto-sterilisation due to acid production during the growth of some organisms. Tryptone Soya Broth formulation conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EU), and Japanese Pharmacopoeia (JP).
