Preparing microbiological culture media providing nitrogen, vitamins, minerals and amino acids.

Tryptone is obtained by pancreatic digestion of casein. Casein is the main protein of milk and is a rich source of amino acids and nitrogen.

This product can be used in preparing microbiological culture media providing nitrogen, vitamins, minerals and amino acids.

Due to the high tryptophan content in tryptone it can be used in detecting indole production.
