Overview
Sabouraud Dextrose Broth (SDB) is the liquid form of SDA, for cultivating and enriching yeasts and moulds and for determining fungistatic activity in sterile and non-sterile products. The high-glucose, slightly acidic environment favours fungi and suppresses bacteria, and pharmaceutical and cosmetic QC commonly use it to prepare inocula for preservative efficacy tests.
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.
