S. cerevisiae XII. Altered forms produced from .S'. globosus: lA-74/349-1-105-18; lB-74/349-l-105-18m-l-4. Altered forms produced from S. paradoxus: 2A-A37-9/2m-l-29; 2B-A37-9/2-l-29d. from S. paradoxus may be referred to 2 species: S. ellipsoi- deus (group 4) and S. cerevisiae (group 2). These data testify to the fact that by cultivating yeasts of the genus Saccharomyces on their specific substrates, it is possible to induce changes in species characters. The scheme of variation is shown in Fig. 3. Fig. 4 shows the intensity of fermentation and the depth at which malt-wort is fermented.
