Tryptone is widely used in microbiology as a nutrient source for growing bacteria. It provides essential amino acids and peptides, making it a key component in culture media for the cultivation of a variety of microorganisms. In laboratories, tryptone is often included in media like Luria-Bertani (LB) broth, which is commonly used for E. coli cultivation. It also supports the growth of fastidious organisms in diagnostic and research settings. Additionally, tryptone is utilized in the production of enzymes, vaccines, and other biotechnological products, where consistent and robust microbial growth is required. Its ability to promote rapid cell proliferation makes it valuable in industrial fermentation processes as well.
