Research progress of functional lactic acid bacteriaстатья
Аннотация: Lactic acid bacteria are closely related to health, in recent years, experts and scholars at home and abroad have been continuously exploring the function of lactic acid bacteria.This article introduced antioxidant, decrease cholesterol, reduce blood press, immune function, produce bacteriocin, and compose vitamins functions of lactic acid bacteria.To provide reference for further development and utilization of functional lactic acid bacteria Introduction.Lactic acid bacteria are gram positive bacteria, non spore, anaerobic, the use of carbohydrates to produce lactic acid bacteria [1] , can be divided into 18 genera, a total of more than 200 kinds.At present, it has been confirmed by domestic and foreign biologists that there is a very close relationship between lactic acid bacteria and health.First lactic acid bacteria separated from the milk, often found in some food and fermentation products in nature, in nature, there are many kinds and wide distribution.Most of them can can ferment lactate are bacteria, some are coccus, some are bacillus, generally do not exercise.They take monosaccharide and disaccharide as substrate, The mainly metabolites are lactic acid, some lactic acid bacteria belong to resistance of anaerobic microorganisms, although they are not aerobic capacity, they can be a typical lactic acid fermentation under anaerobic conditions [2] .The main function of lactic acid bacteria are antioxidant; improve human intestinal function, recovery the balance of human intestinal flora, especially by producing bacteriocin, inhibition of intestinal pathogenic bacteria specific growth and toxin production, balanced intestinal flora; prevention of cardiovascular diseases, including cholesterol lowering effect and reduce the possibility and effect of anti-hypertension, decrease the possibility of occurrence of hypercholesterolemia, atherosclerosis, coronary heart disease and other high-risk disease; enhance human immunity; inhibit the growth of spoilage bacteria; anti tumor; nervous system anti-aging function, recently found that probiotics can regulate the neurotransmitter to prevent Alzheimer's disease and other pathological aging; synthetic vitamins; preservation food; improve food flavor and so on [3] .
