Abstract
The efficiency of five differential media in the detection of wild yeasts was compared. On the basis of the types of wild yeast they are able to detect, these differential media were classified into two groups. Group I consists of actidione medium and lysine medium, and is suitable for the detection of non-Saccharomyces wild yeasts. In this group, the lysine medium detected more species and a higher percentage of wild yeasts than the actidione medium. Group II consists of crystal violet medium, SDM, and Lin's medium, and is suitable for the detection of Saccharomyces wild yeasts. In this group, Lin's medium is superior to crystal violet medium and SDM for wild yeast detection. It is suggested that lysine medium and Lin's medium be employed together for the detection of wild yeasts in the brewery.Keywords
