Tryptone Soy Broth (TSB) is a general-purpose broth which will support the growth of a wide range of micro-organisms and is not intended for use in the diagnosis of disease or other conditions in humans.

Tryptic Soy Broth, a general purpose medium, is commonly referred to as Casein Soya Bean or Soybean-Casein Digest Broth, and abbreviated as TSB. This medium was originally developed for use without blood in determining the effectiveness of sulfonamides against pneumococci and other organisms. Clostridia and non-sporulating anaerobes grow luxuriantly in this broth when incubated under anaerobic conditions. TSB is recommended for testing bacterial contaminants in cosmetics and complies with established standards in the food industry. Enzymatic digest of casein and enzymatic digest of soybean meal are nitrogen sources in TSB. Dextrose is the carbon energy source that facilitates organism growth. Sodium chloride maintains osmotic balance; dipotassium phosphate is a buffering agent.

For casein soya bean digest broth QC tested according to the USP/EP/JP methodology and requirements, please use FSA1280.
