Tryptic Soy Broth- also referred to as Soybean-Casein Digest Medium and commonly abbreviated as TSB is a general purpose, non-selective growth media that supports the growth of most non-fastidious Gram-negative and Gram-positive bacteria as well as many yeasts and molds. It also supports the growth of many obligate anaerobes when incubated anaerobically. Enzymatic digests of casein and soybean meal provide a source of nitrogen, and the inclusion of dextrose provides the main source of carbon for growth. Osmotic balance is achieved through the inclusion of sodium chloride, while dipotassium phosphate serves as a buffering agent to maintain pH. The formulation of BACGroTM TSB conforms to the Harmonized United States Pharmacopeia (USP)1, European Pharmacopeia (EP)2 and Japanese Pharmacopeia (JP)3 Standards.
