Alkali Scientific Sabouraud Dextrose Agar, 1 Kg
Sabouraud Dextrose Agar (SDA) is a widely used general-purpose medium for the cultivation of yeasts, molds, and other fungi. This 1 kg package is suitable for laboratories that require a larger volume of medium for fungal isolation and identification. The high concentration of dextrose in the medium provides a rich source of energy for fungi, while the slightly acidic pH (around 5.6) helps to inhibit bacterial growth. SDA is used extensively in clinical diagnostics for the isolation of pathogenic fungi, as well as in environmental microbiology for the detection of fungal contamination in various settings, including the food and pharmaceutical industries.
