A kind of probiotic composition and its application

Abstract

The invention discloses a probiotic composition and application thereof. The composition contains Bifidobacterium lactis ( Bifidobacterium lactis ) HN019 and Lactobacillus comprising Lactobacillus plantarum ( Lactobacillus plantarum ) CECT 7481 and Lactobacillus brevis ( Lactobacillus brevis ) CECT 7480. Studies have shown that the three strains have a synergistic effect, and the prepared probiotic composition can colonize the oral cavity and antagonize oral Streptococcus mutans, inhibiting its colonization in the oral cavity, thereby preventing and reducing the mutation chain. The role of cocci-induced caries severity.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a probiotic composition and its application. Background technique [0002] Lactic acid bacteria (LAB) have long been recognized as probiotics that provide health benefits, and lactic acid bacteria (LAB) are commonly used as food supplements. In the past studies, many experiments have confirmed that lactic acid bacteria are related to intestinal health, and most of the clinical and experimental data focus on the prevention of gastrointestinal infection, and the research on oral health care is relatively rare. In recent years, with the advancement of microbial technology, people have gradually realized that there is an important relationship between the oral micro-ecosystem and oral health. [0003] The oral cavity is an open environment with a complex micro-ecological system. The dynamic balance of microorganisms in this system is closely related to the health of the oral cav...
