Two new types of specialist culture media are available for the isolation of yeasts and moulds from foodstuffs: Dichloran Rose Bengal Chloramphenicol Agar (ISO) (DRBC Agar) and Dichloran 18% Glycerol Agar (ISO) (DG18 Agar). The new media comply fully with the requirements of ISO 21527-1:2008 and ISO 21527-2:2008 respectively, standards that relate to the enumeration of yeasts and moulds in food and animal feeding stuff. Both products are supplied dehydrated as complete formulations that are ready to prepare without the need for any additional supplementation. DRBC Agar is designed for the enumeration of viable yeasts and moulds in products with a water activity above 0.95. DG18 Agar is for the enumeration of viable osmophilic yeasts and xerophilic moulds in food or animal feed products that have a water activity of 0.95 or less.
