Overview
Sabouraud Agar Modified (Emmons) is an agar (solid) medium, a standard formulation for cultivating yeasts and moulds. Its low pH itself suppresses bacteria; used to isolate, count and maintain yeasts and moulds. STBIO manufactures it from food-grade raw materials in an ISO 22000 certified facility, with a COA for every batch. This is the Halal-certified version.
Principle
Casein enzymatic hydrolysate and pepsin-digested animal tissue provide nitrogen, amino acids, and essential growth factors for fungal metabolism. Dextrose provides the carbon and energy source. In the Emmons modification, the dextrose concentration is reduced to 20 g/L and the pH is adjusted to near-neutral, which improves the recovery of dermatophytes and other fungi compared with conventional Sabouraud Dextrose Agar. Agar acts as the solidifying agent.
Choosing a medium for yeasts and moulds
Potato Dextrose Agar and Sabouraud Dextrose Agar are the two general-purpose media most often used for yeasts and moulds. The former promotes mycelial growth and sporulation for morphological work; the latter's low pH itself suppresses bacteria. Malt-based media suit the cultivation and maintenance of yeasts, while the Czapek range is used for the taxonomy of filamentous fungi such as Aspergillus. Broths are for propagation, agars for enumeration and isolation.

Frequently asked questions
01Do I need to suppress bacterial growth in fungal testing?
It depends on the sample. For foods or environmental samples with high bacterial loads, the pH is usually lowered or antibiotics are added to suppress bacteria. Follow the requirements of your chosen method; we are happy to advise.
02How much powder per litre?
Use 47 g per litre of deionised water; preparation and sterilisation conditions are given on the specification sheet.
