Overview
Sabouraud Dextrose Agar (SDA) is the classic medium for fungi: a high glucose level and slightly acidic pH favour yeasts and moulds while suppressing bacteria, for isolating, cultivating and maintaining dermatophytes, Candida and environmental fungi. It is also the medium specified for total yeast and mould counts in pharmacopoeial microbial limit tests, and is used in volume by pharmaceutical and cosmetic QC.
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.
