Thallism was determined in sake yeasts and other Saccharomyces strains used in wine, shochu and awamori making, and in yeasts isolated from tree exudates. Of 30 strains of sake yeasts, 29 were heterothallic (one strain was not determined), while of 13 strains of wine yeasts, 12 were homothallic and 1 was heterothallic. All 26 strains of shochu yeasts were homothallic, as was the 1 strain of awamori yeast. All 20 strains isolated from tree exudates were homothallic. Of 106 strains of S. cerevisiae isolated from grapes and vineyards, 104 were homothallic and the remaining two were not classified. Thallism can thus be used as a key indicator for separation of sake yeast from other S. cerevisiae strains.
