Peptone from casein is widely used in industrial microbiology as a nutrient source for the growth of microorganisms in large-scale fermentation processes. Peptone from casein, also known as tryptone or peptic casein peptone, is a water-soluble protein hydrolysate obtained from the pancreatic digestion of casein and used as a nutrient source in microbial culture media. It provides a wide range of nutrients, including amino acids, vitamins, minerals, and peptides, which support the growth of diverse microorganisms. It is particularly useful for the cultivation of fastidious and heterotrophic microbes that require complex nutrient sources.

Peptone from casein is commonly used as an ingredient in many microbial culture media for the growth and identification of bacteria, yeasts and molds from various pharmaceutical, environmental, food and beverage samples.
