Bifidobacterium bifidum

From Biology-Online Dictionary | Biology-Online Dictionary



A club-shape, gram-positive, non-motile anaerobic bacterium that is naturally arises in the human body as normal microbiota.


Bifidobacterium bifidum contributed to an enormous benefits on human physiological process such as it helps in better digestion, boost the immune system, lowering the cholesterol levels, increase calcium absorption, good production of lactic acid and uphold anti-tumorgenic effects of colon cancer.

Bifidobacterium bifidum are significantly good as probiotics in the intestine that combat some known pathogenic species and have been develop as remedies in home to lessen diarrhea, yeast infection andirritable bowel syndrome. It also helps in the synthesis of vitamins K and B complex to defend some crucial deficiencies in nutrients that promote balance digestion thereby discouraging the production of histamine.

These bacteria are typically found in branched and curved conformation since their club-shape attributes varies from 0.5-1.3 μm x 1.5 μm that are usually coupled in clusters and V-shape pairs that are able to ferment oligosaccharides in the gastrointestinal tract thus, almost 10% aided in proper breakdown and sugar absorption through coding of ABC transporters to opposed phosphoenolpyruvate-phosphotransferase systems.

Bifidobacterium bifidum produces both D & L-lactic acid but largely high amount of L-lactic acid. The L (+) form is readily absorbed by the human organism and is completely metabolized providing an energetic substrate, whereas the D (-) form of lactic acid is absorbed much slower.
