Potato Dextrose Agar is composed of dehydrated Potato Infusion and Dextrose that encourage luxuriant fungal growth. Agar is added as the solidifying agent. Many standard procedures use a specified amount of sterile tartaric acid (10%) to lower the pH of this medium to 3.5 +/- 0.1, inhibiting bacterial growth. Chloramphenicol acts as a selective age...
Potato Dextrose Agar is used for the detection of yeasts and molds in dairy products and prepared foods.It may also be used for the cultivation of yeasts and molds from clinical specimens.Potato Dextrose Agar with TA (Tartaric Acid) is recommended for the microbial examination of food and dairy products.Potato Dextrose Agar with Chlortetracycline is recommended for the microbial enumeration of yeast and mold from cosmetics.Add 39 gm of Commercial PDA Powder to 1 Litre of Distilled water.Boil while mixing to dissolve.Autoclave 15 min at 121°C.After sufficient incubation, isolated colonies should be visible in the streaked areas and confluent growth in areas of heavy inoculation.
