Survival of yeasts stored after freeze-drying or liquid-drying

We investigated the survival mechanisms of freeze-dried or liquid-dried (L-dried) yeast cells in ampoules. Type strains of various yeasts were freeze-dried or L-dried and sealed in ampoules under high vacuum ( 1 Pa) or low vacuum (4.8 x 10 (4) Pa), then stored at 37 degrees C (accelerated storage test) for up to 17 weeks.
