ABSTRACT:
A yeast strain with high power to produce alcohol by fermentation is produced by a method comprising directly conjugating the haploid of the strain No. 909-1 with each tetrad of the ascospores of the strain No. 180 by spore-to-cell mating, acclimating the resultant zygote in the medium of waste after alcohol fermentation, and acclimating the surviving cells of the zygote in the medium of the beet molasses containing 2-deoxyglucose. The yeast strain produced is designated as Strain M-9 (FERM BP 1481) of genus Saccharomyces cerevisiae. Alcohol is produced by culturing the Strain M-9 in a medium of beet molasses.
