The author and others reported the antigenic structures of several species of the genus Saccharomyces through antigen analyses. However, since they are derived from the standard strains, there must exist the identical antigenic structures among the standard and many other strains as a prequisite for possible service of the species identification.
Therefore, the author collected many authentic strains of the genus, and the identification was carried out by the slide agglutination tests with monospecific or absorbed antisera prepared on the basis of the antigenic structures. Biological characteristics of the strain were examined by usual methods, and then both identifications were compared each other.
The results of the experiments indicated that most strains had the same antigenic structures of the standard strains, and wrong identifications were observed in several cases, if they should be based on biological and serological characteristics. Therefore, the accurate identification must not be performed only on biology, but also on serology, and the antigenic structures of the genus are reliable for the classification of the genus Saccharomyces.
