Description

Technical Field

[0001] The present invention relates to the technical field of probiotics, and in particular to a probiotic liquid agent and its application. Background Art

[0002] Probiotics are a class of microorganisms beneficial to humans and animals. They can colonize in the intestine, improve the balance of the body's microbial flora, enhance the body's immunity, and are beneficial to health. There are various probiotics, including Bifidobacterium, Lactobacillus, yeast, etc. Similarly, if probiotics are taken directly, their survival rate will decrease due to the destruction of adverse environmental factors such as gastric juice before reaching the intestine for colonization. Using suitable technical means to improve the survival rate of probiotics in the body has always been a research hotspot in this field.

[0003] Probiotics have a wide range of applications in the fields of food, medicine, health products, etc. In the food field, probiotics are added to foods such as yogurt, beverages, dairy products, etc. to increase the nutritional value and taste of the food. In the fields of medicine and health products, probiotics are used to treat and prevent intestinal diseases, enhance immunity, etc.

[0004] Traditional probiotic beverages use probiotic solids as raw materials and are rehydrated into liquids, which is rather troublesome in operation. With the increasing enthusiasm of Chinese people for health concepts, the sales volume of probiotic beverages has been increasing year by year. At present, there is no "live bacteria type" probiotic agent with convenient operation and instant consumption and a high number of live bacteria. During the R & D process of the inventor, the applications of this probiotic agent in other fields were also discovered. Summary of the Invention

Detailed Description of the Invention

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Bacillus natto, yeast, lactic acid bacteria, all of the above strains are self-developed by the applicant's company.

[0021] Example 1

[0022] A preparation method of a probiotic agent, characterized by comprising the following steps: S1. Prepare the culture medium, which consists of the following components: 50 g of soybean powder, 50 g of glucose, 5 g of sodium acetate, 5 g of yeast extract powder, and 1 L of water. After preparing the culture medium, sterilize it at 121 °C for 30 min. The sterilization process is also a process of further extracting the nutritional components of the soybean powder, which is beneficial for Bacillus natto, yeast, and lactic acid bacteria to better utilize the nutrients.

[0023] S2. First, activate Bacillus natto, yeast, and lactic acid bacteria. Inoculate Bacillus natto, yeast, and lactic acid bacteria into MRS culture medium respectively and culture them at 37 °C for 2 days, then measure the viable cell count. Then inoculate 10^7 CFU / mL of Bacillus natto, 10^7 CFU / mL of yeast, and 10^7 CFU / mL of lactic acid bacteria into the prepared culture medium and culture it at 37 °C for 15 h.

[0024] S3. Prepare the finished product. Use a filling machine to divide the obtained mixed liquid into 20 mL small strip packages of liquid to obtain the finished product.

[0025] Example 2 - 3 The difference between Example 2 - 3 and Example 1 is that the addition amounts of the components in the culture medium in S1 are different. The culture medium in Example 2 consists of the following components: 10 g of soybean powder, 100 g of glucose, 10 g of sodium acetate, 10 g of yeast extract powder, and 1.5 L of water; the culture medium in Example 3 consists of the following components: 100 g of soybean powder, 10 g of glucose, 1 g of sodium acetate, 1 g of yeast extract powder, and 1.5 L of water.

[0026] Example 4 - 5 The difference between Example 4 - 5 and Example 1 is that the bacterial content added to the culture medium in S2 is different. In Example 4, 10^4 CFU / mL of Bacillus natto, 10^4 CFU / mL of yeast, and 10^4 CFU / mL of lactic acid bacteria are inoculated into the culture medium prepared in S1; in Example 5, 10^9 CFU / mL of Bacillus natto, 10^9 CFU / mL of yeast, and 10^9 CFU / mL of lactic acid bacteria are inoculated into the culture medium prepared in S1. Comparative Example 1 The difference between Comparative Example 1 and Example 1 is that Bacillus natto is not added.

[0027] Comparative Example 2 The difference between Comparative Example 2 and Example 1 is that yeast is not added.

[0028] Comparative Example 3 The difference between Comparative Example 3 and Example 1 is that lactic acid bacteria are not added.

[0029] Examples 1-5 all have good inhibitory effects on miscellaneous bacteria and have good applications in agriculture, soil improvement, and as plant growth agents. Comparing Examples 1-5 with Comparative Examples 1-3, the absence of Bacillus natto, yeast, or lactic acid bacteria has a relatively large impact on the effect of soil improvement and also has a relatively large impact on inhibiting miscellaneous bacteria. These three types of bacteria interact to have relatively good antibacterial, plant growth promotion, and soil improvement effects, and none of them can be missing.

[0030] Application Example 1 Apply the finished product obtained in Example 1 to the prevention of diseases, such as Figure 2 As shown, an obvious antibacterial zone appears in soil fungi, and the finished product (WWBIO) obtained in Example 1 represents the resistance reaction to Fusarium.

[0031] Application Example 2 Apply the finished product (WWBIO) obtained in Example 1 to fertilizers. As Figure 3 shown, comparing the growth of watermelons in Ishikawa Prefecture, Japan, under the same fertilization conditions, 4 seedlings were planted, and WWBIO was only sprayed on 2 of them. Only 2 areas were sprayed with a 500-fold dilution of WWBIO before sowing. After planting, a 1000-fold dilution of WWBIO was sprayed once every 10 days. The watermelons treated with WWBIO are 1.5 times larger than those without treatment.

[0032] As Figure 4 shown, comparing the growth of radishes in Ishikawa Prefecture, Japan, after planting, a 1000-fold dilution of WWBIO was sprayed once every 10 days. The thickness and length of the radishes treated with WWBIO are larger. There are almost no traces of insect bites on the surface. After spraying WWBIO, the soil becomes fertile and the radishes are stress-free.

[0033] Application Example 3 Apply the finished product (WWBIO) obtained in Example 1 to feeds to reduce the stress on dairy cows, thereby improving the meat quality; reduce diseases and accidents; reduce odors, making the cowshed easier to manage.

[0034] Application Example 4 Apply the finished product (WWBIO) obtained in Example 1 to water purification and deodorization to reduce odors, which is also beneficial to improving the working environment, and nearby residents no longer complain.

[0035] This specific embodiment is only an interpretation of the present application and does not limit the present application. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the rights of the present application, they are protected by the patent law.
