Tryptose Phosphate Broth

IBI’s Tryptose Phosphate Broth is a medium recommended for the cultivation of fastidious microorganisms. Tryptose phosphate broth is a buffered broth which can support the growth of fastidious streptococci and meningococci. The addition of 0.1% agar concentration can aid in the recovery of obligate anaerobes. Tryptose peptone and dextrose are a source of carbon, organic nitrogen, and energy. Sodium chloride contributes to osmotic equilibrium and disodium phosphate is a buffering agent.
