Lactic acid bacteria survival improver, survival improvement method, and food composition

摘要

[Problem] The survival of lactic acid bacterial strains such as probiotic bacteria contained in yogurt etc. is improved. [Solving Means] A lactic acid bacterium survival improver including a propionic acid bacterium fermentation product to improve the survival of a lactic acid bacterium. The propionic acid bacterium is a bacterium belonging to the genus Propionibacterium. The bacterium belonging to the genus Propionibacterium is Propionibacterium freudenreichii. Propionibacterium freudenreichii is Propionibacterium freudenreichii ET-3 (FERM BP-8115).
