The survival rates of 10 species of microorganisms were investigated after freeze-drying and preserving in a vacuum at 5 degrees C. The survival rates varied with species. The survival rates immediately after freeze-drying were different among yeast, gram-positive bacteria, and gram-negative bacteria, and the change in the 10-year survival rate was species-specific. The survival rate of yeast, Saccharomyces cerevisiae, was about 10% immediately after drying, and the rate did not decrease… CONTINUE READING
