PURPOSE:To prepare live mold powder of bacterium belonging to the genus Bifidobacterium having a great number of molds showing no reduction in numbers of live molds even in preservation at room temperature, by cultivating a bacterium belonging to genus Bifidobacterium in a medium with specific components. CONSTITUTION:A bacterium belonging to the genus Bifidobacterium is inoculated into a medium containing an edible emulsifying agent comprising a hydrolyzate of milk protein, a saccharide, a yeast extract, and oleic acid as main components, and cultivated anaerobically in a pH range of about 6.8 - about 4.7 while keeping the pH almost constant. The prepared solution containing molds is blended with defatted powdered milk, starch hydrolyzate, sodium glutamate, sodium ascorbate, and a magnesium salt, and lyophilized. |
