Premium Potato Dextrose Agar (PDA) is a gold-standard dehydrated culture medium widely used in global microbiology laboratories and food safety industries. Formulated to comply with APHA and FDA industry specifications, our PDA medium delivers consistent, accurate, and reproducible results for fungal detection and microbial analysis.
Specially engineered for the isolation, cultivation, and enumeration of yeasts and molds, this medium is a fundamental solution for microbiological quality control in dairy products, processed foods, and raw food materials. The optimized formula creates a weakly acidic environment with a stable pH value of 5.6 ± 0.2 at 25°C, which effectively inhibits bacterial growth and eliminates bacterial contamination interference, ensuring pure fungal growth and precise test data.
Our PDA medium adopts a scientific premium formula composed of high-purity potato infusion, dextrose, and agar. The balanced nutrient composition strongly stimulates the growth and reproduction of various fungi, supports sporulation of dermatophytes, and maintains the activity of fungal stock cultures. It also enables accurate strain differentiation by observing pigment production in mycological research and experimental analysis.
Simple & Standard Preparation Method
No complex configuration process is required. Dissolve 46.0g of dehydrated PDA powder in 1L of distilled water, heat and stir to full boiling, sterilize via autoclave at 121°C for 15 minutes, then cool to 40–45°C and pour into Petri dishes. The prepared medium presents a uniform yellowish to milky white translucent gel, providing an optimal growth environment for yeasts and molds. For the best experimental results, incubate inoculated plates at 28°C ±1°C for 48–96 hours.
Wide Application Scenarios
- Food microbiological quality inspection and safety testing
- :Cultivation, isolation and counting of yeast and mold strains
- Maintenance and preservation of fungal standard cultures
- Mycological research, strain identification and pigment observation experiments
- Dairy and food factory routine microbial monitoring
Strict Storage & Quality Guarantee
Store the dehydrated PDA powder in a tightly sealed container at 5°C–30°C, keeping away from direct sunlight and humid environments. Under standardized storage conditions, the product features a long shelf life of 3 years with stable performance. We recommend avoiding the use of agglomerated, discolored, or deteriorated medium powder to ensure experimental accuracy.
Trusted by laboratories and food testing institutions worldwide, our Potato Dextrose Agar features high stability, strong fungal targeting, and easy operation. It is an essential staple medium for daily microbial testing, scientific research, and food safety quality control, helping every laboratory obtain reliable and standardized experimental data.
