Since the 70 s was established Hamburg, Germany first micro ecology research institute on, micro ecology has gradually developed into a new subject and remarkable micro ecology is life science branch, as a study of organisms normal badge biota and its host mutually dependent and interacting law science, and it involves organism and its internal environment (including microbial, biological chemical and biological physical environment) adapt to the problem, and human health is closely related to the human medical experience the treatment medicine and preventive medicine, is to care medical moves forward, the micro ecology is health care medical theory and practical application of the basic subject.
China was one of the founders of micro ecology KangBai professor noted that: in the human body or biology foreign must adapt to environment and the internal must adapt to its internal microscopic environment, to health development growth, according to this topic, 2011 American bei yuan company was set up MYBEAR micro ecological research center.
(a) Normal flora physiological function
1, Antagonistic action: a factor can restrain or influence another factor play a role.
2, Biological barrier - planting resistance - inhibiting pathogenic bacteria colonization.
3, Change the pH, H2O2, occupied, nutrition for, antibiotics and bacteriocin, etc
(1) Nutrition action to participate in SanYang element metabolism; Synthetic vitamin
(2) The immune function produce sIgA, activated CD4 + T cell - produce IFN, etc
(3) Tumor-suppressor effect inhibiting tumor growth
(4) Dichotomous/lactobacillus - degradation nitrous acid amine
4, Stimulate the mononuclear cell to gobble up the ability to improve.
5, Anti-aging effect.
(2) The human body each parts of the micro ecological system:
1, Nutrition aid digestion function beneficial bacterium can produce protease, amylase, lipase, cellulose decomposing enzyme, pectinase, phytic acid enzyme and so on, with gastrointestinal inherent enzyme together and jointly promote feed digestion and absorption, improve feed utilization, Lactic acid bacteria, lactic acid bacteria produce double discrimination, intestinal pH value is reduced, promote the vitamin D and calcium, phosphorus, iron and other minerals trace element absorption, has very good nutrition effect, and can prevent minerals, vitamin, protein metabolism disorder the nutrition such as the occurrence of metabolic disease.
2, Resisting the digestive tract infection, enhance immunity, resist stress
Probiotics another significant feature is to prevent intestinal infection. Lactic acid bacteria, bacillus can produce some peptides antibacterial substances, such as acidophilic bacteria element, lactose rhzomorph, bacitracin and so on, which may restrain or kill pathogenic bacteria, reduce inflammation and allergic reaction occurs, for a variety of pathogenic microorganism infection have very good control effect. When an animal is under feed replacement, weaning, transportation, disease and antimicrobial drug used a large amount for a long time, such as stress effect, can cause in the digestive tract these beneficial bacterium group of equilibrium destruction and become sick. Probiotics can quickly built up good advantage bacterium group, so that the damaged micro ecological environment recovery, and improve the ability to resist stress.
(3) Microecologic health (Microecological modulator) probiotics refers to the known beneficial microorganisms (animal body or the nature of existence), the use of modern biological project technology culture, fermentation and other special technology processing made of biological agents. Probiotics contain beneficial living bacteria and its metabolites and culture.
Probiotics also known as probiotics, and direct feeding microorganisms (DFM), etc. By adjusting the micro dysbiosis, keeping microecological balance of preparation, the international has its into three types:
1, Probiotics (Probiotics) also called probiotic; he is the living bacteria preparation and its metabolites, and Antibiotics (Antibiotics) instead of material
2, Prebiotics (Prebiotics) is to point to to selectively promote host-plant intestinal some one or several beneficial bacteria (probiotics) growth breeding, and not be host digest substances, through the beneficial bacteria multiply, restrain harmful bacteria growth
3, Accrete hormone (Synbiotics) refers to the probiotics and prebiotics coexisting preparation, after take can make into the configuration of probiotics in prebiotics, under the action of any fruitful, and multiply, and make the effect of probiotics significantly more lasting. Accrete element is the microecologic health development direction
(4) Micro ecological other knowledge
1, Probiotics characteristics of the obvious
Probiotics through the effective supplement in the digestive tract of human body the beneficial microbe, improve the gastrointestinal flora balance, to improve the baby metabolism and food absorption ability, strengthen the disease resistance, from but attain to promote the growth and the prevention and control of the digestive tract disease multiple roles. Unit weight of the viable count (colony count units: CFU) is one of the important indexes of products.
2, And micro ecological related concept and product
Prebiotics or probiotic: refers to promote probiotics (mainly bifidobacterium) grow and breed a kind of structure and properties of different substances (most is a peptic oligosaccharide). They don't be (or is seldom) host enzyme system and other bacterial enzyme system decomposition, namely these substances oral intake, the esophagus, stomach and small intestine reach large intestine later settled in the bifidobacterium and lactobacillus and decomposition use, so as to promote its growth breeding. Most prebiotics seldom directly on the body action, and mainly through the probiotics indirectly play physiological function. GeShengYuan or connation agent: refers to contain probiotics and prebiotics ingredients of the products.
According to the MYBEAR long-term study, found that probiotics have nutritional and prevention and treatment of disease two big functions, but probiotics itself doesn't contain functional ingredients and nutrient, also does not contain cure disease drug ingredients, so probiotics have immunity, but the vaccine has a qualitative difference.
