Introduction:

"First, I'll sort out two questions you'll ask. 1. What is lactic acid bacteria? Lactic acid bacteria are a group of Gram-positive bacteria (non spore) that can produce a lot of lactic acid from fermentable carbohydrates (mainly sugars). All the bacteria that can produce lactic acid from the fermentation process of glucose or lactose are collectively referred to as lactic acid bacteria. This is a very complex group of bacteria, can be divided into at least 18 genera, a total of more than 200 species. Except for a few, most of them are essential and have important physiological functions in the human body, which widely exist in the human intestinal tract. It has been confirmed by biologists at home and abroad that intestinal Lactobacillus is closely related to health and longevity. At the same time, lactic acid bacteria also widely exist in the intestines of livestock and poultry, many foods, materials and a few clinical samples. Lactic acid bacteria can not only improve the nutritional value of food, improve the flavor of food, improve food preservation and added value, but also the special physiological activity and nutritional function of lactic acid bacteria are attracting more and more attention. A large number of studies have shown that lactic acid bacteria can regulate the normal flora of gastrointestinal tract, maintain microecological balance, improve food digestibility and biological value, reduce serum cholesterol, control endotoxin, inhibit the growth and reproduction of spoilage bacteria and the production of spoilage products in intestinal tract, produce nutrients, stimulate tissue development, thus affecting the nutritional status, physiological function, cell infection and drug resistance of the body Effects, toxic reactions, immune reactions, tumorigenesis, aging process and sudden emergency response. Therefore, the physiological function of lactic acid bacteria is closely related to the life activities of the body. It can be said that if lactic acid bacteria stop growing, it is difficult for people and animals to survive healthily. Because of this, lactic acid bacteria are widely used in light industry, food, medicine and feed industry. Lactic acid bacteria is a kind of probiotics existing in human body. Lactic acid bacteria can ferment carbohydrates into lactic acid, hence the name. Probiotics can help digestion, contribute to the health of human intestines, so they are often regarded as healthy food, added in yogurt. There are hundreds of bacteria in human intestines, and the number is more than one million. Among them, probiotics are beneficial to human health, represented by Bifidobacterium and Enterococcus faecium, and harmful bacteria are harmful to human health, represented by Escherichia coli and Clostridium perfringens. Probiotics is a huge flora, and harmful bacteria is also a large flora. When probiotics are dominant (accounting for more than 80% of the total), the human body will remain healthy, otherwise it will be in a sub-health or non-health state. Long term scientific research results show that probiotics represented by lactic acid bacteria are essential to human body and have important physiological functions. The number of probiotics directly affects people's health and life span. The long-term research results of scientists have proved that lactic acid bacteria are very important for people's health and longevity. The number of lactic acid bacteria in human intestinal tract will gradually decrease with the growth of people's age. When people are old or sick, the number of lactic acid bacteria may decrease by 100 to 1000 times, until the elderly die completely. At ordinary times, there are 50 times more healthy people than patients, and 60 times more long-lived people than ordinary people. Therefore, the actual situation of the number of lactic acid bacteria in the human body has become an important indicator of whether people are healthy and long-lived. Due to the wide application of broad-spectrum and powerful antibiotics, probiotics mainly composed of lactic acid bacteria in human intestinal tract have been seriously damaged, and their resistance has gradually declined, resulting in more and more diseases and great threat to health. Therefore, it is very important to increase the number of lactic acid bacteria in human intestinal tract. Internationally recognized lactic acid bacteria, is considered to be the safest strain, but also the most representative of probiotics in the intestine. The more the number of probiotics represented by lactic acid bacteria, the better. It is also completely consistent with the conclusion of Nobel Prize winning biologist michenikov's "longevity theory", that lactic acid bacteria = probiotics = longevity bacteria. In the face of the increasingly powerless situation of antibiotics, human beings are constantly seeking new and more effective biological antibacterial products. The developed countries in the world first recognized and created the immunotherapy revolution represented by the use of lactic acid bacteria. According to the results of Swedish scientists, it is better to drink lactic acid bacteria directly than antibiotics in the treatment of stomach and large intestine inflammation, and the risk is almost zero. In Japan, Lactobacillus products account for more than 85% of the Japanese dairy market. In the past 20 years, the average height of Japanese young people has increased by 15 cm, and the average life expectancy of the population has reached 85 years, ranking first in the world. These are the direct health benefits of lactic acid bacteria products. There are hundreds of bacteria in human intestines, and the number is more than one million.

These are the direct health benefits of lactic acid bacteria products. The physiological functions of lactic acid bacteria: 1. Prevention and treatment of lactose intolerance (abdominal distension, diarrhea and other symptoms when drinking fresh milk) commonly suffered by some ethnic groups. 2. Promote the absorption of protein, monosaccharide, calcium, magnesium and other nutrients, and produce a large number of beneficial substances such as vitamin B group. 3. Increase intestinal beneficial bacteria, improve the function of human gastrointestinal tract, restore the balance of intestinal flora, form antibacterial biological barrier, and maintain human health. 4. Inhibit the reproduction of spoilage bacteria, eliminate the toxin produced by spoilage bacteria, and remove intestinal garbage. 5. Inhibit cholesterol absorption, reduce blood lipid and blood pressure. 6. Immunoregulation, enhance human immunity and resistance. 7. Anti tumor and cancer prevention. 8. Improve the activity of SOD enzyme, eliminate the free radical of human body, have the function of anti-aging and prolonging life. 9. Effective prevention of female genitourinary system bacterial infection. 10. Control the level of toxin in human body, protect the liver and enhance the detoxification and detoxification function of liver. A few of them are heterotypic fermentation, such as Leuconostoc mesenteroides, which is an important strain for dextran production in pharmaceutical industry, but it is also a kind of harmful bacteria in sugar industry, which often makes sugar juice sticky and unable to be processed. Lactobacilli are rod-shaped, single or chained, sometimes filamentous and pseudobranched. According to the different products of glucose utilization, it can be divided into homotype fermentation group and heterotype fermentation group. Most of them can ferment lactose without lactic acid, and the pH can be reduced to below 6.0 after fermentation. In this family, lactobacillus is the most important, most of which are commonly used in industry, especially in food industry. It is found in dairy products, fermented plant foods such as pickles, sauerkraut, silage, and human intestines, especially in infants. Thermophilic fermentation bacteria are commonly used in industrial production of lactic acid. For example, L. delbrueckii, whose optimal growth temperature is 45 ℃, is widely used in the production of lactic acid and calcium lactate. 2. Where to buy lactic acid bacteria? Taobao
