چکیده
The advantages of freeze-drying are obvious. It is a convenient method for the preservation and long-term storage of a wide variety of microorganisms. However, special precautions are needed for the preservation of microorganisms sensitive to desication, light, oxygen, osmotic pressure, surface tension and other factors. During several years of experimentation I have developed various new methods and have optimised freezedrying conditions to achieve successful lyophilization of a large collection of difficult and fragile microorganisms.
