Lab M has added two new products to its portfolio of specialist culture media for the isolation of yeasts and moulds from foodstuffs: Dichloran Rose Bengal Chloramphenicol Agar and Dichloran 18% Glycerol Agar.

The new media comply with the requirements of ISO 21527-1:2008 and ISO 21527-2:2008 respectively. Both products are supplied dehydrated as complete formulations that are ready to prepare without supplementation.

Widespread in nature, yeasts and moulds pose a contamination risk to foodstuffs during processing, packaging and storage. When creating media for their isolation and culture it is essential to balance the growth of selected organisms with a degree of control, in order to prevent overgrowth and enable efficient colony counting. The incorporation of the antifungal agent dichloran in the new media restricts the spreading of mucoraceous fungi and controls the colony size of other genera.

Dichloran Rose Bengal Chloramphenicol Agar is designed for the enumeration of viable yeasts and moulds in products with a water activity above 0.95.

Dichloran 18% Glycerol 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.
