Tryptic Soy Broth is a nutrient-rich universal medium free of inhibitors and targets to enumerate a broad spectrum of bacteria, yeast, and molds. The medium is supplemented with peptones from casein and soymeal to provide an enhanced carbon source, which promotes the growth of the microflora. The broth medium is used during sterility testing due to its wide range of specificity.
