It is primarily used in microbiological research and laboratory settings to study yeast growth and metabolism. By providing essential nutrients like nitrogen, vitamins, and minerals, it allows researchers to create controlled environments for yeast cultivation. This is particularly useful in genetic studies, where specific amino acids or other nutrients can be selectively added or omitted to observe their effects on yeast behavior. It is also employed in industrial applications, such as optimizing yeast strains for fermentation processes in brewing, winemaking, and biofuel production. Additionally, it serves as a base medium for developing diagnostic tools to test yeast susceptibility to antifungal agents.
