The invention discloses
lactobacillus plantarum capable of relieving
enteritis and
toxicity of
polystyrene nano-plastics, and the preservation number of the
lactobacillus plantarum is CGMCC (China General
Microbiological Culture Collection Center) NO.31420. The
lactobacillus plantarum can be used for relieving
enteritis and
toxicity of
polystyrene nano-plastics. The strain is obtained by separating and purifying baby
feces, and can grow on an MRS culture medium, and the
bacterial colony is round, off-white, smooth and opaque. Experiments show that the
lactobacillus plantarum can effectively adsorb PS-NPs, promote the PS-NPs to be discharged along with excrement, reduce accumulation of the PS-NPs in organs, and significantly reduce
toxicity and
inflammatory response of organs such as
liver and kidney of mice. In addition, the strain can repair the intestinal
barrier function, regulate
liver metabolism and relieve
enteritis symptoms. The invention further provides a
probiotic preparation containing the strain, and the
probiotic preparation can be prepared into granules, capsules, tablets or oral liquid and the like and is used for preventing or treating
intestinal injury and inflammatory diseases caused by PS-NPs. The strain is safe and efficient, and has a wide application prospect.
