Abstract
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.
Claims14
A biologically pure culture of a microorganism Pseudomonas syringae which has all the identifying characteristics of strain KCCM-10039 having ice nucleating activity at room temperature.
A biologically pure culture of the microorganism Pseudomonas syringae KCCM-10039, wherein said culture retains ice nucleating activity when cultured or stored in solution at room temperature.
A method for forming ice particles using an ice nucleating microorganism, which comprises the steps of:
- (a) forming an aqueous suspension of an effective amount of a biologically pure culture of an ice nucleating microorganism Pseudomonas syringae KCCM-10039;
- (b) introducing said aqueous suspension into a water source whose temperature is maintained below about 25.degree. C. to form a mixture;
- (c) cooling said mixture until ice is formed;
- and
- (d) distributing and freezing said mixture.
