Overview

Peptone from Casein, also known as Tryptone, is a complex mixture of peptides and free amino acids produced by enzymatic digestion (hydrolysis) of casein, the primary protein found in milk. It is widely used in microbiology laboratories as a high-quality nitrogen source for bacterial cultivation.

Tryptone is particularly valued for its high content of free amino acids, including tryptophan, making it suitable for microorganisms that require tryptophan for specific metabolic or biosynthetic pathways. Its low carbohydrate content makes it ideal for use in media formulations where fermentable sugars may interfere with analytical or biochemical test results.
