A medium recommended by the Harmonised European Pharmacopoeia for the cultivation of a wide range of micro-organisms.
Conforms to USP/EP/JP performance specification. The medium is also commonly referred to as tryptone (or tryptic) soy broth and abbreviated to TSB. Enzymatic digests of casein and soya bean act as a source of nitrogen and glucose is a carbon source in the form of a fermentable carbohydrate. Sodium chloride maintains the osmotic balance and dipotassium hydrogen phosphate acts as a buffering agent.
