Potato Dextrose Agar (PDA) - 500g Highlights

  • Microbiological Growth Medium: Potato Dextrose Agar (PDA) is a widely used nutrient medium for the cultivation of fungi and yeasts. It is prepared by boiling potatoes to extract starch and nutrients, then adding dextrose (sugar) and agar as a solidifying agent.
  • Ideal pH for Fungi: PDA typically has a slightly acidic pH (around 5.6) after autoclaving, which is optimal for the growth of most fungi and inhibits the growth of bacteria. This makes it a selective medium for fungal isolation.
  • Versatile Applications: Beyond general fungal cultivation, PDA is used in various applications including mycology research, plant pathology for isolating plant pathogens, and in the food industry for detecting spoilage organisms.
  • Storage and Shelf Life: Prepared PDA plates should be stored inverted in a refrigerator at 4°C to prevent dehydration and contamination. Properly stored, they can remain viable for several weeks.
  • Sterilization Method: PDA is typically sterilized using an autoclave at 121°C (250°F) for 15-20 minutes. This ensures the elimination of any contaminating microorganisms before use.
