Peptone from meat is widely used in industrial microbiology as a nutrient source for the growth of microorganisms in large-scale fermentation processes. Peptone from meat is a water-soluble protein hydrolysate obtained by the proteolytic digestion of meat sources 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 useful for the cultivation of fastidious and heterotrophic microbes that require complex nutrient sources.

Peptone from meat 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, and food and beverage samples. The high sulphur content makes meat peptone suitable for the detection of bacteria producing hydrogen sulfide.
