AI Technical Summary
Technical Problem
The prior art cannot obtain selenized polysaccharides with high selenium content through microbial transformation, and cannot effectively supplement the body's selenium intake.
Method used
Separate and screen a straw of Lacticaseibacillus Rhamnosus Z160 strains. The strain can convert inorganic selenium to selenium -rich polysaccharides, and the selenium content is higher than 80 μg/g.
Benefits of technology
By using the Z160 strain to prepare extracellular polysaccharides, efficient selenium conversion and selenium -rich polysaccharide production have been achieved. It has good antioxidant and cholesterol reduction activity, which can be used to prevent hyperlipidemia and prolong life.

Abstract
The invention discloses a lactobacillus rhamnosus Z160 strain and an application of the lactobacillus rhamnosus Z160 strain in preparation of selenium-rich exopolysaccharides. The Z160 strain is separated from fermented pickled Chinese cabbages and is preserved in Guangdong Microbial Culture Collection Center on September 5, 2024, and the preservation number is GDMCC NO: 65104. When the Z160 strain is cultured, the yield of the exopolysaccharide can be increased by adding a selenium source, the obtained exopolysaccharide is high in selenium content and has good antioxidant and cholesterol-reducing activity, the Z160 strain can be used for preparing the selenium-rich exopolysaccharide, and the prepared selenium-rich polysaccharide can also be used for preparing products for preventing and treating hyperlipidemia and prolonging the life of animals. Besides, the selenium-rich exopolysaccharide prepared from the Z160 strain can inhibit formation of biofilms of pathogenic bacteria such as Listeria monocytogenes, and the obtained polysaccharide can be used for preventing and treating diseases related to the biofilms, cleaning and maintaining instruments polluted by the biofilms and the like.
