Exopolysaccharides-producing lactobacillus plantarum for adsorbing monophthalate effectively

Abstract

The invention relates to the biotechnical field, particularly relates to the field of production and development of functional lactic acid bacteria, more particularly relates to exopolysaccharides-producing lactobacillus plantarum for adsorbing monophthalate effectively. The strain number of the exopolysaccharides-producing lactobacillus plantarum for adsorbing monophthalate effectively is RS20D, and the exopolysaccharides-producing lactobacillus plantarum for adsorbing monophthalate effectively is registered and preserved in China General Microbiological Culture Collection Center (CGMCC) with the preservation number of CGMCC No.13272 and the preservation date of November 14, 2016. The lactobacillus plantarum RS20D provided by the invention is functional lactic acid bacteria which has acid resistance, grows well in an environmental condition of pH 3.0-9.0, and particularly has the characteristic of adsorbing monophthalate and producing exopolysaccharides, for example, the lactobacillus plantarum RS20D is developed to a health-care food or drug which is taken for a long time to improve intestinal flora, and the damage of a phthalate plasticizer on a human body is reduced; or, the lactobacillus plantarum RS20D is input to a fermenting diary product or a cheese product, so that the sensory characteristic of the product can be improved.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to the field of production and development of functional lactic acid bacteria. Specifically, it relates to a strain of exopolysaccharide-producing lactobacillus plantarum that effectively absorbs phthalic acid monoester. Background technique [0002] Lactic acid bacteria exopolysaccharide (LAB EPS) is a mucus or capsular polysaccharide secreted by lactic acid bacteria during growth and metabolism. The lactic acid bacteria strains producing exopolysaccharides can be directly applied to the production of fermented milk to replace or reduce the use of thickeners, improve the viscosity, texture and taste of yogurt products, and prevent shrinkage and whey precipitation. At the same time, the exopolysaccharide of lactic acid bacteria also has good physiological activities, such as anti-tumor, immune regulation and anti-oxidation, and can also be used as a prebiotic to promote the growth of o...

Problems solved by technology

However, in the food industry, there is no effective way to remove phthalate contamination in food

At present, there are no literature or patent reports on the use of lactic acid bacteria to remove phthalates and their toxic metabolites-phthalate monoesters
