A comparative serological study was carried out using 22 strais of Saccharomyces cerevisiae which included 9 strains of sake yest, and 16 strains of Saccharomyces species other than S. cerevisiae. Slide agglutination and double diffusion analysis were applied to 8 antisera, 81 absorbed sera and 5 monospecific sera. It was found that the strains of S. cerevisiae were divided into three groups by composition of the unit antigens : 1) 8 out of 9 strains of sake yeast and 1 strain of brewer's yeast showed the unit antigens 1,2 and 4; 2) 2 strains of brewer's yeast contained antigens 1 and 3; 3) the remaining 11 strains including 1 strain of sake yeast were composed of the unit antigens 1,2,4 and 5. Strains of other Saccharomyces were found to have generaly the same antigenic composition as the third group of S. cerevisiae. Double diffusion and paper chromatograohic analysis revealed that the serological defferences between yeasts were caused by cellwall polysaccharides containing mannan.
