Proteose peptone is widely used in microbiology and biotechnology as a nutrient source for cultivating bacteria and other microorganisms. It provides essential amino acids and peptides that support the growth and proliferation of cells in various culture media. In the food industry, it is utilized as a supplement to enhance the nutritional profile of products, particularly in fermentation processes for dairy and meat products. Additionally, proteose peptone finds application in vaccine production, where it serves as a component in the growth medium for producing antigens. Its ability to promote cell growth and protein synthesis makes it a valuable ingredient in research laboratories and industrial applications.
