Bifidobacterium animalis bacteria

Bifidobacterium animalis strains display the following characteristics typical for the genus Bifidobacterium: Gram-positive, non-motile, non-spore forming, irregular rod-shaped anaerobes. Glucose is fermented using the characteristic enzyme fructose-6-phosphate phosphoketolase in the so-called Bifidus-shunt. Dextrin, a-D-glucose, maltose, maltotriose, D-raffinose, and sucrose are fermented; the starch is not fermented. Bifidobacterium animalis and Bifidobacterium lactis were categorized as two distinct species and now are considered as Bifidobacterium animalis with two subspecies: animalis and lactis. Among different commercially available strains, Bifidobacterium animalis spp. lactis BB-12 and Bifidobacterium animalis spp. lactis DN-173010 has been studied extensively.
