LACTOBACILLUS SALIVARIUS AND METHOD FOR PREPARING METABOLITE THEREOF, COMPOSITION OF LACTOBACILLUS SALIVARIUS AND METABOLITE THEREOF AND USE OF THE COMPOSITION

摘要

Provided is a Lactobacillus salivarius belonging to Lactobacillus salivarius subsp. Salivarius, and deposited in China General Microbiological Culture Collection Center with an accession number CGMCC NO: 3606. Further provided is a method for preparing a metabolite of the Lactobacillus salivarius, wherein the Lactobacillus salivarius is as described above. Further provided is a composition, comprising viable strains of the Lactobacillus salivarius and/or the metabolite of the Lactobacillus salivarius prepared as described above. Further provided is a use of the composition in preparation of drugs for prevention and/or treatment of cancers and a method for treating and/or preventing cancers. The viable strains of Lactobacillus salivarius and the metabolite of Lactobacillus salivarius provided in the present invention can both remove the genotoxicity of 4-NQO in vivo, thus exerting an effect of effectively preventing and/or treating cancers.
