What Is Lactobacillus Acidophilus Bacteria?
Lactobacillus acidophilus is not only in the stomach, it is also the main probiotic in the human small intestine. The stomach of pathogenic bacteria that can survive in the stomach is a small "disinfection workshop" because of the strong acidity of the gastric juice.

- Lactobacillus acidophilus is not only in the stomach, it is also the main probiotic in the human small intestine. The stomach of pathogenic bacteria that can survive in the stomach is a small "disinfection workshop" because of the strong acidity of the gastric juice.
Lactobacillus acidophilus
- Lactobacillus acidophilus belongs to the genus Lactobacillus and Gram-positive bacilli. The end of the rod is round and mainly exists in the small intestine. It releases lactic acid, acetic acid, and some antibiotics that work against harmful bacteria.
Culture characteristics of Lactobacillus acidophilus
- [1] Incubate on an anaerobic agar plate at 35 ° C for 48 h. Formation of small (approximately 0.5 mm diameter), reticular, raised, rough surfaces, and curled edges.

Health benefits of Lactobacillus acidophilus
- Adjust the intestinal flora balance and inhibit the proliferation of intestinal undesirable microorganisms. Lactobacillus acidophilus has an antagonistic effect on pathogenic microorganisms. Lactobacillus acidophilus can secrete avidin (acidolin, acidophilin, 1aetocidon), which antagonizes the intestinal pathogenic bacteria.
- A starter consisting of a mixture of Lactobacillus acidophilus (A for short) and Bifidobacterium (B for short). Ingestion of dairy foods containing these two kinds of live bacteria is good for the digestive organs, especially for infants and young children with gastrointestinal disorders and some patients with gastrointestinal disorders caused by long-term oral antibiotics. After milking, it can quickly restore the normal balance of the intestinal flora and inhibit the proliferation of spoilage bacteria, so it has a good nutrition and health effect.
Features of Lactobacillus acidophilus
- Lactobacillus acidophilus-regulating stomach and intestinal microecology
- When it comes to bifidobacteria, many people know that it is the main probiotic in the large intestine; while Lactobacillus acidophilus is not only in the stomach, it is also the main probiotic in the human small intestine. These two are huge in number and support each other, and play a role in promoting human health by maintaining the micro-ecological balance of the entire gastrointestinal tract.
- Lactobacillus acidophilus regulates the micro-ecological environment in the entire gastrointestinal tract of the human body from top to bottom. "Lower" means that in the large intestine, they can also release substances that are beneficial to the growth of other probiotics such as bifidobacteria, increase the number of probiotics in the large intestine, and enhance their vitality.
- The higher the proportion of probiotics in the human intestine, the better the micro-ecological environment and the younger and more active the intestine. Intestinal health is not only reflected in good digestion and absorption, normal stools, and difficulty in infecting intestinal diseases; for the whole body, sufficient and viable probiotics reduce the production of toxins in the body and reduce the liver by inhibiting various harmful bacteria Detoxification burden; Bifidobacterium and Lactobacillus acidophilus can also produce lactic acid and acetic acid after fermentation in the intestine, which can increase the utilization of calcium, phosphorus, and iron, promote the absorption of iron and vitamin D, and produce vitamin K and vitamin B. It can also reduce the absorption of cholesterol and reduce the harm of radiation to the human body.
Information about Lactobacillus acidophilus
How to get Lactobacillus acidophilus
- The survival rate of Lactobacillus acidophilus in the stomach can generally reach 80%, but if the Lactobacillus acidophilus is administered orally, their viability will still be affected; if they are all embedded, it will not be possible Play its beneficial role in the stomach. Therefore, we first select a generation of live bacteria directly bred from the fungus mother, and then apply half of them to double-layer embedding technology, which not only co-feeds the stomach and intestines, but also guarantees the activity of live bacteria in the intestines.
- The advantage of double embedding technology is that after the outer layer of gelatin is dissolved in the intestine, the inner layer of protein can also help
- According to the Ministry of Health Announcement No. 25 of 2011, Lactobacillus acidophilus is a strain that can be used in foods for infants and young children.
- Properties of Lactobacillus acidophilus: freeze-dried powder, viable count of Lactobacillus acidophilus: 3.0 × 10cfu / g, moisture: 4.0%, if the bacterial solution, the moisture is> 80%.
Lactobacillus acidophilus proliferation mode
- In nutrient-rich MRS culture towels, the effects of adding oligosaccharides on the proliferation of three lactic acid bacteria, such as isomalto-oligosaccharides, have a certain proliferation effect on Lactobacillus acidophilus, Lactobacillus lactis, and Streptococcus lactis [2] .
- Colony logarithm of oligosaccharides for lactic acid bacteria proliferation
- Oligosaccharides are small aggregates connected by 2 to 10 monosaccharide units through glycosidic bonds, between monomeric monosaccharides and highly polymerized polysaccharides. It has been reported abroad that oligosaccharides can promote the proliferation of intestinal bifidobacteria and lactic acid bacteria, inhibit the growth of E. coli, etc., can also stabilize the intestinal environment, and improve the intestinal mucosal immune function. It has also been reported that [3] fructooligosaccharides can only increase the number of microorganisms in feces and cannot promote the number of bifidobacteria in the intestine.
- It can be seen from this experiment that both isomalto-oligosaccharide and oligosaccharide can promote the proliferation of Lactobacillus acidophilus, Lactobacillus lactis and Streptococcus lactis to a certain extent.
- Oligosaccharides, as bifidus factors, cannot be used by the digestive tract and pathogenic bacteria, and can only be used by probiotics, so that probiotics can multiply in large numbers, and as proliferative factors of probiotics, enhance the competitive advantage of probiotics. This experiment [2] carried out the observation on the in vitro proliferation of 3 strains of lactic acid bacteria under different nutritional conditions.
- The results of this experiment [2] show that in a nutrient-poor medium, oligosaccharides can significantly promote the proliferation of lactic acid bacteria, which has positive significance for clinical intestinal recovery of human and animal organisms. The growth and proliferation of intestinal beneficial flora such as lactobacillus and bifidobacteria require higher nutritional levels, while conditional pathogens such as E. coli have relatively low nutritional requirements. When breeding in the intestine, the nutritional requirements for their growth are obtained Easier. In the normal and healthy body intestinal environment, the beneficial flora gets sufficient nutrition, the growth and proliferation is relatively strong, and it also has a certain inhibitory effect on the harmful flora; when the body's intestinal disorder, a large number of harmful bacteria multiply consume nutrients, which is beneficial At this time, the nutritional conditions of the flora are insufficient, and the growth and proliferation are affected, which further exacerbates the deterioration of the intestinal environment. At this time, taking oligosaccharides can effectively exert its proliferation effect on lactobacillus, and its characteristics that are not used by harmful bacteria, determine that it can specifically promote the growth of bifidobacteria and lactobacillus to achieve regulation The effect of intestinal flora balance [2] .
