Induction of Freeze-sensitive Mutants from a Freeze-tolerant Yeast, Torulaspora delbrueckii

スポンサーリンク

概要

• 論文の詳細を見る

• Freeze-sensitive strains of yeast were induced from a freeze-tolerant yeast Torulaspora delbrueckii by incubation with ethyl-methane sulfonate as a mutagen. A maximum ratio of mutation was attained by the incubation at 30℃ for 75min. One-hundred and fifty strains of freeze-sensitive yeast were selected by plating-culture for the first screening. The freeze-tolerance ratio of each strain was examined based on the fermentative activity before and after freezing in liquid medium and dough. Strain 60B3 showed the highest freeze-sensitivity in a pre-fermented frozen dough (pre-fermented at 30℃ for 2h, and frozen at -20℃ for 7days)among eight strains finally selected.
