Potato Dextrose Agar - 5 Kg
- Used for the isolation, identification, and cultivation of fungi
IBI’s Potato Dextrose Agar is used for the isolation, identification, and cultivation of fungi. Potato dextrose agar powder is also used in the cultivation and isolation of yeasts and molds from dairy and food products. Lowering the pH to 3.5 ± 0.1 inhibits bacterial growth and aids in the isolation of fungi.
Store at room temperature (less than 30⁰C), tightly sealed, and protect from moisture and light.
pH @ 25°C: 5.6 ± 0.2
Note: Grams per/liter may be adjusted to achieve desired performance.

Mix 39.0 gm of the medium in 1 L of purified water until evenly dispersed. Heat with repeated stirring and boil for
one minute to dissolve completely. Distribute and autoclave at 121°C for 15 minutes. If desired, the pH of the
medium can be adjusted to 3.5 ± 0.1, prior to pouring plates, by the addition of 14 ml of sterile 10% tartaric acid to
melted sterile medium cooled to 45-50°C. Avoid reheating medium after the addition of the tartaric acid solution.
