Example Embodiment

[0032] Example 1

[0033] A probiotic preparation for improving the microecological balance of the upper respiratory tract, which is composed of streptococcus A bacteria powder, Tetrasars bacteria powder, Bifidobacterium infantis and Lactobacillus acidophilus, and the streptococcus type A bacteria powder accounts for the probiotic bacteria preparation The weight percent is 30%; the number of viable bacteria in the probiotic preparation is 10 10 .

Example Embodiment

[0034] Example 2

[0035] A probiotic preparation for improving the microecological balance of the upper respiratory tract is composed of streptococcus alpha bacteria powder, tetrasars bacteria powder, Bifidobacterium longum, Bifidobacterium infantis and Lactobacillus acidophilus. The weight percentage of the powder in the probiotic preparation is 60%; the number of viable bacteria in the probiotic preparation is 10 15 .

Example Embodiment

[0036] Example 3

[0037] A probiotic preparation for improving the microecological balance of the upper respiratory tract, which is composed of streptococcus A bacteria powder, Tetrasars bacteria powder, Bifidobacterium breve and Lactobacillus acidophilus, and the streptococcus type A bacteria powder accounts for the probiotic bacteria preparation The weight percentage is 50%; the number of viable bacteria in the probiotic preparation is 10 12 .

[0038] The preparation method of the probiotics preparation in the present embodiment is as follows:

[0039] A. Preparation of streptococcus type A bacteria powder

[0040] After adding whey protein and fructooligosaccharide to the liquid medium, autoclave at 121°C for 20min, cool to 37°C, inoculate with Streptococcus A, and continuously culture at 37°C until the bacterial content reaches 1×10 5 / ml, centrifuge with a low-temperature high-speed centrifuge to obtain wet cells;

[0041] The wet thalline is suspended in a skimmed ...

Abstract

The invention discloses probiotics capable of improving microecological balance of upper respiratory tracts and a preparation method thereof, belonging to the technical field of biology. The probiotics comprise alpha streptococcus powder, micrococcus tetragenus powder, bifidobacterium powder and lactobacillus acidophilus powder, wherein the alpha streptococcus powder accounts for 30-60% of the probiotics by weight; the viable count of the probiotics is 10<10>-10<15>. The probiotics not only are beneficial to stabilization of microfloras of respiratory tracts and can effectively prevent upper respiratory tract infections and avoid upper respiratory tract diseases but also can still play a role of probiotics, regulate microflora balance of gastrointestinal tracts and enhance the resistance of human bodies to foreign pathogenic bacteria after the probiotics powder enter the gastrointestinal tracts with saliva swallowing.

Description

technical field [0001] The invention relates to a probiotic preparation, in particular to a probiotic preparation for improving the micro-ecological balance of the upper respiratory tract and a preparation method thereof, belonging to the field of biotechnology. Background technique [0002] The lower respiratory tract of a healthy human body, especially the part below the small bronchi, the lungs and the chest cavity are completely sterile. The nasopharynx, as the beginning part of the respiratory tract, is the passage connecting the lower respiratory tract with the outside world. Any pathogenic bacteria entering the human body must first Colonization of the nasopharynx can then further cause corresponding pathological reactions in the body. The nasopharynx is sterile when the baby is born. Through the close contact with the air environment and the surrounding people, general aerobic bacteria such as Streptococcus A and Staphylococcus albus appear in the nasopharynx and thr...
