Protoplast fusion of Saccharomyces bakers' yeast between freeze-tolerant strain and bakers' yeast strain was carried out in an attempt to combine these two characteristics in the hybrids. The mitochondrial markers were used in one parental strain by introducing petite mutants and mutation to antibiotic resistance. The fusion products were analysed for the cellular DNA content, intact chromosomal DNA molecules and dough-raising abilities in both sweet dough and frozen dough.
