Used as a growth medium in microbiology laboratories to cultivate fungi and bacteria due to its rich nutrient content derived from potato infusion and dextrose. Commonly employed in quality control testing of food, pharmaceuticals, and cosmetics to detect microbial contamination. Also utilized in fungal culture maintenance and identification in research and clinical settings. Its balanced composition supports the growth of a wide range of microorganisms, making it ideal for general-purpose microbial cultivation.
