Polyamine Metabolism and Applications

Antigenic differences among strains of Saccharomyces cerevisiae Hansen 1883 and Saccharomyces uvarum Beijerinck 1898 were analyzed with respect to the proton magnetic resonance spectra of alkali-extracted mannans and the gel filtration profiles of the oligosaccharides of these mannans obtained by acetolysis. The strains of both species could be divided into serotypes Ia, Ib, and II. The serological relationships of these strains were found to correlate with the proton magnetic resonance spectra of the cell wall mannans. The gel filtratin profiles of the acetolysis oligosaccharides of type Ia, Ib, and II strains of both species were also characteristic for each type or subtype. Based on these findings, it is proposed that S. cerevisiae and S. uvarum be combined into one species with two main serotypes. S. uvarum is thus a later subjective synonym of S. cerevisiae.
