What is Bifidobacterium animalis?
Bifidobacterium animalis is a Gram positive anaerobic bacterium belonging to the genus Bifidobacterium, commonly found in the intestinal tract of mammals, and is an important probiotic. It has strong acid and bile resistance, can colonize in the human intestinal tract, and assists in maintaining the balance of intestinal flora.
It contains multiple subspecies, such as B. animalis subsp. lactis, which is widely used in the food industry such as yogurt and probiotic supplements. Its safety is widely recognized and it has a positive effect on intestinal health.

Bifidobacterium bifidum (B.bifidum), is part of the Bifidobacterium family. This bacteria is a Gram-positive bacteria that is non-motile, anaerobic, and non-spore forming. It is rod shaped and can be found living in clusters, pairs, or even independently. B.bifidum is found in the colon, lower small intestine, breast milk, and often in the vagina. The optimized growth temperature for B.bifidum is 36～38℃. Its metabolic mechanism allows heteromorphosis to ferment glucose, galactose, fructose etc. to produce Lactic Acid as well as Enzymes, Vitamins etc. 
B.bifidum is the most popular Bifidobacterium probiotic bacteria, being used for a long time. Although it can be found in both infants and adults, the Bifidobacterium specie is predominant in the infants’ gastro-intestinal tract, being considered a growth factor. Recent research shows that people with big longevity have a higher Bifidobacterium ratio.

Bifidobacterium animalis is a viable, freeze-dried microbial powder, typically off-white to light beige in color. It is anaerobic but exhibits good stability under controlled low-moisture and oxygen-barrier storage conditions. It ferments a variety of carbohydrates to produce short-chain fatty acids, primarily acetate and lactate.

Bifidobacterium animalis is a Gram-positive, anaerobic, rod-shaped probiotic bacterium naturally found in the gastrointestinal tracts of humans and animals. It is known for its high acid and bile tolerance, allowing it to survive passage through the upper digestive tract. It is widely used as a probiotic supplement for its digestive and immune health benefits. The subspecies Bifidobacterium animalis subsp. lactis (e.g., BB-12 strain) is among the most extensively studied probiotic strains worldwide.
