Higher glycerol-productive yeast mutants were bred from allylalcohol resistants and pyrazole resistants of Saccharomyces cerevisiae Kyokai No. 7(K-7) and its haploid strain. All the higher glycerol-producing mutants obtainecd from allylalcohol resistants of K-7 diploid were respiratory-defficient strains, with the exception of only one. Other higher glycerol-producing mutants(pyrazole resistants derived from K-7 diploid and allylalcohol resistants derived from K-7 haploid)were not respiratory deficient. The acquisition of respiratory deficiency by K-7 caused an increase in glycerol production, but this alone was not sufficient to obtain higher producing ability. Two higher glycerol-producing(lower ADH activity)mutants were subjected to small-scale sake making. Both mutants not only produced higher glycerol than K-7 but also as much ethanol as K-7.
