Intented use and fields of application

Sabouraud-Dextrose-Agar is an universal nutrient medium used for the isoaltion and cultivation, enumeration of yeast and moulds and dermatophyta. Sabouraud Dextrose Agar is supplemented with 4% Dextrose in order to promote the growth of the microorganisms. The low pH promotes spore development and pigment formation in yeasts and fungi which in addition, inhibits the growth of bacteria. Thus SAD is a selective growth medium.

This Nutrient medium meets the requirements for the methods of the EP/USP/JP. The use of Sabouraud Dextrose Agar is recommended for the analysis of Candida albicans in non-sterile pharmaceuticals.

The addition of Lecithin, Tween 80 and Histidine components neutralises the inhibitory effects of aldehydes, phenols, hexachlorophene, chlorhexidine, formaldehyde and quarternary ammonium compounds used for preservatives, cleaning and disinfection agents.
