PURPOSE:To obtain stabilized bacteria belonging to the genus Bifidobacterium, by adjusting a solution containing the bacteria belonging to the genus Bifidobacterium and a stabilizer to a specific pH, and freeze-drying the bacteria. CONSTITUTION:A stabilizer, e.g. an amino acid, is added to a solution containing bacteria belonging to the genus Bifidobacterium, e.g. Bifidobacterium infantis ATCC15697, and pH is adjusted to 7-10. The resultant adjusted solution is then freeze-dried (at <=30 deg.C shelf temperature under about 0.1Torr vacuum degree). |
