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.
Bifidobacterium, along with Lactobacillus, are some of the most well-known probiotics and are an important part of your flora. These good bacteria are lactic-acid producing bacteria (LAB), just like Lactobacillus, and they both produce vitamins, bacteriocins (antibacterial chemicals) and antibiotic-like substances.
