Abstract
A new differential medium, cupric sulphate medium, used for the detection of wild yeasts has been formulated and tested. This medium suppressed the growth of culture yeasts and supported that of most non-Saccharomyces wild yeasts. It is not suitable for the detection of Saccharomyces wild yeasts. The contaminating wild yeasts in yeast samples and swab samples were easily detected by this medium. Since Lin's medium or modified Lin's medium is suitable for the detection of Saccharomyces wild yeasts, it is suggested that they be used in conjunction with cupric sulphate medium for detecting a more complete spectrum of wild yeasts.Keywords
