This is a selective medium for the isolation of yeasts and fungi and is particularly suitable for use in sterility testing. The low pH (5.6) of the medium is inhibitory to most bacteria and many diagnostic features such as spores and pigmentation are well developed on this medium. The formulation of this medium conforms to the requirements of the United States Pharmacopoeia. Lecithin & Polysorbate 80 (Tween 80) are added to inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds & Tween neutralises phenols, formalin, hexachlorophene and in combination with the Lecithin ethanol).
