Tryptone, Powdered Media

Tryptone is a pancreatic digest of casein. It is utillized as a source of nitrogen in many culture media for growing bacteria as well as fungi. Tryptone supplements media for the cultivation and maintenance of fastidious aerobic and facultative microorganisms, such as E. coli and Pseudomonas species. It is used to supplement media in the cultivation of anaerobes.

• The lack of detectable carbohydrates makes this peptone an excellent choice for bacterial studies based on fermentation reactions.
• Its high level of tryptophan makes it useful in the production of indol.
