General description

Peptone from casein (Tryptone) is a pancreatic digest of casein, used as a nitrogen, vitamins, and minerals source in culture media. It supports the growth of fastidious and non-fastidious micro-organisms. It can also be used for indole production because of its high tryptophan concentration. It is used as an additive to nutrient media in the production of toxins, vaccines, enzymes, and further biological products.

Application

Peptone from casein (Tryptone) is used for detecting bacteria in dairy products, drinking and wastewater, and in antibiotic test media.
