Sabouraud-Dextrose-Agar acc. to EP/USP/JP with LTH (SAB-LTH)
Recommended by the Harmonised European Pharmacopoeia, supplemented with Lecithin, Polysorbate 80 (Tween 80) and L-Histidine
|Format:||Petri Dish, 90mm|
|Storage conditions:||Dry, in closed bag, at 15 – 22°C.|
|pH:||5.6 ± 0.2 at 25°C|
Universal Nutrient medium for the isoaltion and cultivation and enumeration of yeast and moulds and dermatophyta. Sabouraud Dextrose Agar supplemented with 4% Dextrose promotes the growth of these microorganisms. The low pH promotes spore development and pigment formation in yeasts and fungi and additionally inhibits the growth of bacteria. Thus SAD is a selective growth medium.
This Nutrient medium meets the requirments 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 neutralise the inhibotory effects of aldehydes, phenols, Hexachlorophene, chlorhexidine, formaldehyde and quarternary ammonium compounds used for preservatives and cleaning and disinfection agents.
