MICROORGANISM VARIANT HAVING ICE NUCLEUS FORMING ACTIVITY ATNORMAL TEMPERATURE AND PRODUCTION OF SNOW OR ICE USING THE SAME

摘要

Disclosed herein are a new mutant of Pseudomonads having ice nucleating activity and an improved method for making snow and ice using it. More particularly, Pseudomonas syringae SO754 of the present invention, which is derived from the parent strain, Pseudomonas syringae SO7 can retain its ice nucleating activity at room temperature. Further, Pseudomonas syringae SO754 of the invention retains its high activity during the fermentation, recovery and drying steps and during the storage without freezing treatment.
