The versatility of Bifidobacterium longum as a lactic acid microorganism is reflected in its capacity to resist under harsh conditions such as stomach acid, bile, pH fluctuations, and gastrointestinal passage.
(FYI in some research studies, Bifidobacterium lactis was thought to be B. animalis or streptococcus lactis.) Bifidobacterium Lactis is a very powerful transient probiotic bacteria. Scientific studies have proven that B. Lactis enhances immunity, fights tumor growth, improves digestion and can lower cholesterol.
