ABSTRACT:
There is disclosed a method for recovery of a microorganism having ice nucleating activity from a fermentation medium which comprises the steps of (a) bringing the temperature of the medium to a temperature of about 15.degree. C. or less, (b) forming a concentrate of the medium while maintaining the temperature of about 15.degree. C. or less, (c) running the concentrate into a cryogenic fluid to form frozen pellets of the concentrate and (d) freeze drying said pellets at a temperature below 25.degree. C.
