This survey is focused on the techniques of detection of wild yeasts in brewery laboratory. The experimental part of the work deals with the ability of 19 strains of culture and wild yeasts to grow on wort, hopped-wort and lysine agar, and on media containing monoiodacetic acid, crystal violet and copper sulphate. Growth of yeasts on WLN agar, on MYGP agar with actidione and on MYGP agar at 37 deg C was also monitored. Photographs of representative colonies of yeast strains on various agar media are presented. The practical usefulness of the media in brewery laboratory was evaluated.
