PROBLEM TO BE SOLVED: To stabilize sporogenous lactobacillus having health-promoting effect and useful for foods, pharmaceuticals, etc., in aqueous solution by storing the sporogenous lactobacillus in an acidic aqueous solution having a specific pH and containing a hydrophobic substance having a specific logP value. SOLUTION: A sporogenous lactobacillus such as Bacillus coagulanse having health-promoting effect such as intestinal environment improving effect and useful for foods and pharmaceuticals is stabilized in an aqueous system such as aqueous solution by storing the lactobacillus in an aqueous solution having pH of <=4 and containing a hydrophobic substance having a logP value of >=2.5. The hydrophobic substance is preferably one or more materials selected from hydrophobic proteins, hydrophobic peptides, hydrophobic amino acids, food oils and fats, antioxidants, emulsifiers, etc. |
