General description

Potato Dextrose Agar is used for the cultivation of bacteria, fungi, yeast, and molds. The low pH makes the media selective for acid tolerant bacteria, fungi, mold, and yeasts. It is used for studying ascospore dispersal. Potato extract serves as a source of carbon, nitrogen, minerals, vitamins, and other essential growth nutrients. Dextrose acts as source of carbohydrate.

Application

PDA is recommended for use in: -
  • The isolation and enumeration of yeasts and molds from food and dairy products
  • Stimulating sporulation
  • Maintaining stock cultures of fungi
  • Differentiating various dermatophytes based on pigment production
