Sabouraud Dextrose Agar is a nonselective medium for the cultivation of fungi, especially dermatophytes. It is the standard medium for recovery and maintenance of fungi in the clinical laboratory. The original formulation has an acidic pH of 5.6, which suppresses bacterial growth. The Emmons modification to the original formula features a higher pH (6.9) and a reduced dextrose level (2%), yielding greater recovery of fungi, although with less selectivity. BBL™ Sabouraud Dextrose Agar prepared plates are deep-filled in order to minimize the drying effects of prolonged incubation.
