Freeze drying
The process of freeze-drying(lyophilization) involves the removal of water vapour by vacuum sublimation from the frozen state.
Freeze-drying has been widely used for many years as one of the preferred method for long-term preservation. Freeze-drying is particularly suitable for collections which supply cultures on demand because of its broad applicability, economy of storage space and ease of distribution. Freeze-drying is the most technologically complex of the preservation methods in use. It is labour intensive and requires the highest level of technical skill. The method is suitable for many types of microorganisms including most bacteria, yeast, sporing-fungi and some viruses, algae and protozoa.
One of the major advantages of freeze-drying is that the ampoules are particularly
