Difference between Saccharomyces cerevisiae and its elipsoideus variety.Peer-reviewed article

A. KOCKOVÁ-KRATOCHVÍLOVÁ, M. FISCHEROVÁ

To distinguish Saccharomyces cerevisiae from its variety S. c. elipsoideus and S. vini the utilization of lower dextrines and formation of pseudomycelium were taken as criteria. Chromatographic analyses disclosed that no dextrines were involved in the process, but only maltotriose. Classification method was used to decide, whether differences in maltotriose utilization and formation of pseudomycelium provide a sufficient base for distinguishing two varieties. The mentioned criteria are not sufficient for distinguishing two kinds of yeast. It is also extremely difficult to distinguish varieties. During prolonged cultivation of pure cultures differences existing within one kind are gradually smoothed, which holds true in the first line of rather unstable properties.
