Electric charges on the cell surface at pH 3.0 were investigated by boundary moving electrophoresis [Sumino et al. : J. Ferment. Technol., 44,594 (1966)] in 384 strains of Saccharomyces species, including 152 strains of sake yeast, 80 strains of distiller's yeast, 15 strains of brewer's yeast, 20 strains of baker's yeast, 77 strains of wine yeast, 10 strains of shaohsing yeast, and 30 strains isolated from tree exudates. Of the 152 strains of sake yeast, 144 showed a positive charge, 3 showed neutral charge, and 5 showed a negative charge. On the contrary, of the 80 strains of distiller's yeast, 73 showed a negative charge and 7 showed a positive charge. Of the 152 strains including brewer's yeast, baker's yeast, wine yeast, shaohsing yeast and yeast isolated from tree exudates used in this investigation, all strains carried a negative charge. Characteristics of S. sake (sake yeasts) may be further clarified by this difference in the electric charge on the cell surface.
