Abstract
The present invention provides a new ice nucleus-forming bacterium strain, Xanthomonas campestris INXC-1 (FERM BP-4191), a process for the cultivation of the new ice nucleus-forming bacterium, an ice nucleus-forming substance containing the ice nucleus-forming bacterium, and the uses of the ice nucleus-forming substance. Further, a method for lyophilizing a food using the strain as an ice nucleus-forming substance is disclosed; wherein the method is carried out by adding the strain to the food, thereby freezing the food, and then vaporizing moisture from the frozen food to effect drying. The food types which may be lyophilized using the method include tea extracts, fruit juices, soy sauce, sauces, drippings, soups fermented soy bean paste and agar.
