Tryptone Soy Broth (TSB)
Tryptone-Soy Broth is a universal nutrient medium suitable for a wide range of uses. In light of its excellent nutritive value, it favors the growth of most fastidious microorganisms. It is used in the pharmaceutical industry to satisfy sterility tests and its formula is that listed in the United States Pharmacopoeia for specific and non-specific germs. It responds also to the formulations described in quality control norms established for cosmetic products, as well as in animal health.
The typical composition corresponds to that described in the European Pharmacopeia.
Available in 500g and 5 kg package.
In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.
The combination of Tryptone and papaic digest of soybean meal leads to a synergy between the protein supply of casein and the carbohydrate supply of soybeans. This leads to the optimal growth of a large number of species.
Glucose is an energy source.
Sodium chloride maintains osmotic balance.
Dipotassium phosphate acts as a buffer to maintain a constant pH.
