Frozen dough-resistant, practical baker's yeast
The invention provides a diploid or higher polyploid, practical baker's yeast with good frozen dough resistance. This is produced through mating with one or more NTH1 gene-disrupted, haploid yeasts as produced through gene manipulation of disrupting the NTH1 gene in a haploid yeast of which the diploid is practical baker's yeast. The reduction in the trehalose content of the yeast is significantly prevented even when used in frozen dough, and the frozen dough containing the yeast is well resistant to long-term freezing and storage.
