Basic information
Bifidobacterium longum belongs to the genus Lactobacillus, Gram-positive bacteria, no plasmid, no spores, no flagella, no motility, strict anaerobic bacteria.
Product specifications
Active lactic acid bacteria content ≥ 100 billion cfu/g, powder, packed in aluminum foil bags, 1kg/bag.
Suitable growth environment
1. The optimal growth temperature of Bifidobacterium longum is 36-38°C, the growth temperature range is 20-45°C, and the pH range is 6.5-7.0. It generally does not grow when the pH value is below 4.5-5.0 or above 8.0-8.5.
2. This strain is a strict anaerobic bacterium without catalase activity. The tolerance to oxygen varies with the number of passages. When there is oxygen, a small amount of catalase is activated to remove a small amount of hydrogen peroxide, and hydrogen peroxide The presence of will destroy the enzymes produced by carbohydrate metabolism, which will lead to difficulties in the growth of bacteria.
Growth characteristics
1 Culture characteristics: It can be cultivated in the laboratory and can be cultivated in MRS medium.
2 Biochemical characteristics: Bifidobacterium longum does not produce carbon dioxide, propionic acid and butyric acid in the process of carbohydrate metabolism, but takes acetic acid and lactic acid as the main metabolites, and also produces a small amount of formic acid and succinic acid; Digested fibers or polysaccharides produce acid in large quantities to inhibit harmful bacteria.
Benefits
Bifidobacterium longum is its ability to boost the immune system. Studies have shown that this strain can enhance the production of natural killer cells, which are important for fighting off infections and diseases. Additionally, Bifidobacterium longum has been shown to reduce inflammation in the gut, which can further support the immune system.
Another important benefit is its ability to improve digestion. This probiotic strain can aid in the breakdown and absorption of nutrients, which can reduce bloating and other digestive issues.
