Used widely in microbiology for cultivating and isolating fungi and bacteria, especially from food, environmental, and clinical samples. Supports the growth of a broad range of microorganisms due to its rich nutrient content derived from potato infusion and dextrose. Commonly used in quality control testing of food and pharmaceuticals to detect yeast and mold contamination. Also employed in agriculture and research for identifying plant pathogens and studying microbial colonies on solid media. Its slightly acidic pH helps suppress bacterial growth while promoting fungal development, making it ideal for selective isolation.
