Hardy Diagnostics Tryptic Soy Broth (TSB) with Lecithin and Tween® 80 is recommended for the cultivation of a wide variety of fastidious and nonfastidious microorganisms from nonclinical specimens, when the neutralization of disinfectants is desired. This medium can also be used for sterility testing and to test the microbial content of water.
This product is not intended to be used for the diagnosis of human disease.
The formulation of Tryptic Soy Broth with Lecithin and Tween® 80 is prepared according to the United States Pharmacopeia (USP) standard formula for Soybean-Casein Digest Broth.(3) It is also included in approved procedures in the Compendium of Methods for the Microbiological Examination of Foods and Standard Methods for the Examination of Water and Wastewater.(1,2)
Hardy Diagnostics Tryptic Soy Broth (TSB) with Lecithin and Tween® 80 contains digests of soybean meal and casein which provide amino acids and other nitrogenous compounds to support microbial growth. Sodium chloride is added to maintain cellular osmotic equilibrium. Glucose provides an energy source. Lecithin and Tween® 80 are added to the formulation to neutralize germicidal or disinfectant residues. Neutralization of these residues reduces their inhibitory effect which would ultimately result in the lowering of the microbial count. Quaternary ammonia compounds are neutralized by lecithin while phenolic disinfectants and hexachlorophene are neutralized by Tween® 80. Together, lecithin and Tween® 80 neutralize ethanol.(1,2)
Ingredients per liter of deionized water:*
|Pancreatic Digest of Casein||17.0gm|
