Method of preparing fermented soymilk via Paenibacillus bovis, fermented soymilk prepared via Paenibacillus bovis and application of fermented soymilk

Abstract

The invention discloses a method of preparing fermented soymilk via Paenibacillus bovis. The method comprises the steps of inoculating Paenibacillus bovis CGMCC No. 8333 as a fermenting bacterial agent to soymilk, and carrying out fermenting to obtain fermented soymilk. Fermented soymilk prepared via the method and application of the fermented soymilk in resistance to dental caries are also disclosed. The fermented soymilk prepared herein helps significantly reduce the formation quantity of Streptococcus mutans biofilm. A novel use of the fermented milk prepared via the Paenibacillus bovis CGMCC No. 8333 in resistance to dental caries is disclosed herein; the fermented milk has a good application prospect. Compared with other strains with a soymilk fermenting function or culture media which the strains may grow and breed, the Paenibacillus bovis CGMCC No. 8333 enables the fermented soymilk prepared therewith to gain the activity of significantly inhibiting the formation of Streptococcus mutans biofilm.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a preparation method of fermented soybean milk. In addition, the invention also relates to a fermented soybean milk and its application. Background technique [0002] Dental caries, commonly known as caries, tooth decay, is a bacterial disease, can be secondary to pulpitis and periodontitis, and even cause alveolar bone and jaw inflammation. If it is not treated in time, the lesion will continue to develop, forming cavities, and eventually the crown will be completely destroyed and disappeared. The final result of its development is tooth loss. Dental caries is characterized by high incidence and wide distribution. The disease is the main common disease of the oral cavity and one of the most common human diseases. The World Health Organization has listed it as one of the three major diseases of human beings, along with tumors and cardiovascular diseases. [0003] There...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the research reports on dental caries treatment focus on controlling or reducing the number of Streptococcus mutans in the oral cavity. However, a healthy oral environment is generally in a state where harmful bacteria and beneficial bacteria reach a balance. Excessive reduction of harmful bacteria will Bring the imbalance of oral flora, and then cause other adverse reactions of the human body

In addition, some clinically used bactericidal drugs against Streptococcus mutans, such as silver ammonium nitrate and other compounds, have strong side effects, and long-term use will stain teeth, so they are not suitable for anterior teeth treatment

The risk of dental caries can also be reduced by reducing the production of Streptococcus mutans biofilm without disrupting the inherent balance of oral flora or causing side effects, but there are relatively few reports in this regard, especially the research related to microbial fermentation products is extremely limited , fermented products that inhibit the biofilm formation of Streptococcus mutans are quite scarce
