2 Core Product Advantages
In general, this agar grows, separates and counts yeast and mold. It fits daily quality check for dairy, processed food and raw food. Moreover, it keeps steady weak acid value at pH 5.6±0.2 under 25°C. This feature stops most bacteria from growing. In turn, it avoids bacteria pollution for pure fungal growth.

3 Scientific Formula & Functional Features
The PDA powder adopts balanced high-purity ingredients, including potato infusion, dextrose and agar. Furthermore, its rich nutrients accelerate fungal growth and reproduction. Meanwhile, it supports dermatophyte sporulation. Also, it keeps fungal stock cultures active. Lastly, it helps technicians identify strains via colony pigment observation in mycological tests.
4 Standard Medium Preparation Steps
Importantly, this medium features easy preparation with no complex operation. First, dissolve 46.0g dehydrated powder into 1L distilled water. Second, stir and heat the liquid until boiling. Third, sterilize the mixture at 121°C for 15 minutes in an autoclave. Fourth, cool liquid to 40-45°C, then pour it into Petri dishes. The finished medium is milky translucent gel. In addition, incubate plates at 28°C±1°C for 48-96h to get optimal test effects.
5 Main Application Fields
Correspondingly, PDA covers multiple lab and industrial scenarios:
- Daily food microbial safety inspection
- Yeast and mold separation, culture and enumeration
- Long-term preservation of standard fungal strains
- Academic mycological research and strain identification
- Regular microbial monitoring for food and dairy factories
6 Storage Rules & Quality Notice
To keep PDA good quality, seal powder and store it at 5°C to 30°C. Keep it away from sunlight and wet places. With correct storage, it can be used for 3 years. Nevertheless, do not use lumpy, faded or spoiled powder. It will make test results wrong. Learn easy storage skills via Our Lab Agar Storage Blog (Valid Internal Link).
7 Product Final Advantage
Finally, this PDA medium gains trust from global testing labs. It has stable performance, strong fungal specificity and easy operation. Thus, it acts as essential lab supplies for daily testing and food safety control. It can help users obtain standardized and reliable microbial test data.
