Sabouraud Dextrose Agar is one of several media available for theisolation of yeasts and fungi suitable for use in all areas of mycology. Sabouraud Dextrose Agar is a modification of a medium originally described by Sabouraud. The tryptone and meat peptone provide the nitrogen and vitamins required for organism growth in Sabouraud Dextrose Agar. The high concentration of dextrose is included as an energy source and in tandem with the acidic pH (5.6) facilitates the growth of fungi whilst providing limited selective properties. Higher levels of selectivity can be achieved against bacterial species by the addition of chloramphenicol.
NB: This is a basic medium only and contains no additional supplements.

Mycological agar is a selective medium for the isolation of pathogenic fungi, particularly dermatophytes, from clinical specimens. Enzymatic digest of soybean meal provides the required carbon, nitrogen and vitamins. Glucose is an energy source for the metabolism of fungi. The addition of chloramphenicol further reduces the risk of bacterial contamination when processing material that may be heavily contaminated with coliforms. Cycloheximide should also be added (0.4g/L) to suppress the growth of commensal yeasts and saprophytic fungi.
