Gastric peptone is widely used in microbiology as a nutrient source for cultivating bacteria and other microorganisms. It provides essential amino acids and peptides that support the growth of a variety of organisms in laboratory settings. This makes it a key component in culture media for diagnostic, research, and industrial applications. Additionally, it is utilized in the production of vaccines and enzymes, where it serves as a substrate for microbial fermentation. Its ability to promote robust microbial growth also makes it valuable in studying microbial physiology and metabolism. In the food industry, gastric peptone can be used as a supplement to enhance the nutritional profile of certain products. Its versatility and effectiveness in supporting microbial growth make it a critical ingredient in both scientific and industrial contexts.
