Sabouraud Dextrose Agar (SDA) is a premium, specialized culture medium meticulously formulated for the isolation, differentiation, and maintenance of fungi, including yeasts and molds. Trusted by laboratories worldwide, it is an indispensable tool in pharmaceutical testing, food safety analysis, clinical microbiology, and environmental monitoring — delivering consistent, reliable results for all microbial analysis needs.
Our SDA features an optimized formula that ensures superior fungal growth while inhibiting unwanted bacterial contamination. Each liter of medium contains 10.0 g of mycological peptone (providing essential nitrogenous compounds for fungal nutrition), 40.0 g of glucose (supplying a high-energy carbon source to support vigorous fungal proliferation), and 15.0 g of agar (delivering a stable, firm gel matrix for colony observation). The final pH is precisely adjusted to 5.6 ± 0.2 at 25°C, a key feature that creates an ideal acidic environment for fungal growth while suppressing bacterial growth — a critical advantage for accurate fungal isolation and identification.
Available in a dehydrated form, our SDA appears as a free-flowing yellowish powder, ensuring easy handling and consistent reconstitution. When prepared correctly, it forms a clear, yellowish gel that provides optimal visibility for observing fungal colony morphology. The preparation process is straightforward: simply suspend 65 g of dehydrated SDA in 1 liter of distilled or deionized water, mix thoroughly, heat with frequent agitation, boil for 1 minute, and autoclave at 121°C (15 lbs) for 15 minutes — no specialized equipment or expertise required, saving your lab valuable time.
To ensure long-term usability and performance, our SDA comes with clear storage guidelines: store the tightly capped container of dehydrated medium at 5-30°C, with a shelf life of 3 years. For prepared medium, keep it at 2-8°C in a light-protected environment to maintain its integrity and effectiveness. Each batch undergoes strict quality control testing: after incubation at 20-25°C for 48-72 hours, fungal cultural characteristics are carefully observed to ensure consistency and reliability across every use — meeting the highest standards for laboratory media.
Key features of our Sabouraud Dextrose Agar include: an effective growth environment optimized for fungi, versatile applications across pharmaceuticals, food safety, cosmetics, and clinical specimens, and rigorous quality control to guarantee consistent results. Please note that this product is for laboratory use only; do not use dehydrated medium that is past its shelf life, caked, or discolored.
Whether you’re conducting microbial limit tests, isolating pathogenic fungi, or maintaining fungal cultures, our SDA is designed to deliver exceptional performance. Backed by an optimized formula, easy preparation, and compliance with global laboratory standards, it’s the preferred choice for laboratories seeking reliable, user-friendly fungal culture media.
