Problems solved by technology

After lead enters the human body and is absorbed, transported and redistributed, it accumulates in different organs, resulting in an increase in the lead load. Finally, 90%-95% of the lead is mainly deposited in the bones, and the half-life in the bones can reach 25 years, which continuously triggers lead damage. The toxicity of lead exposure affects multiple systems such as nerves, hematopoiesis, blood vessels, immunity, liver, kidney, and bones. Children in the growth and development period are particularly sensitive to lead exposure, and the damage caused by lead exposure cannot be completely repaired

Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the present invention clearer, preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] 1. Screening of lactic acid bacteria that adsorb lead ions and research on its adsorption mechanism

[0034] 1 Experimental materials

[0035] According to the "List of strains that can be used in food" issued by the Ministry of Health, this study selected 37 strains from the strain bank of Suohuayi Laboratory, School of Food Science, Southwest University for follow-up experiments. The strains in this strain bank were isolated from traditional fermented milk products in plateau areas such as Hongyuan, Qinghai, and Xinjiang, and traditional fermented vegetables in Sichuan and Chongqing.

Abstract

The invention discloses Lactobacillus plantarum LP33 (Lactobacillus plantarum LP33) with a preservation number of CCTCC NO: M 2019594 and the application of the Lactobacillus plantarum in the preparation of health products, foods and medicines that promote lead excretion. , Enriching the types of fermented products and establishing a resource bank of lactic acid bacteria have important practical significance, and at the same time bring new hope to the prevention of lead poisoning.

Description

technical field [0001] The invention relates to a strain of lactobacillus plantarum capable of promoting lead excretion and its application in food, health products and medicines. Background technique [0002] Lead (Pb) is a non-essential toxic heavy metal element that widely exists in nature and can cause many acute and chronic diseases. Lead is widely used in the manufacture of lead-acid batteries, wire sheaths, lead pipes, chemical reaction vessels, pigments and pesticides. The world consumes millions of tons of lead every year, of which less than 25% will be recycled, and the remaining 75% can enter the environment through waste water, waste gas, waste residue, etc., causing pollution, endangering animals, plants and human health. Most lead and its compounds are infected through the respiratory tract and digestive tract, a small part is infected through the skin, and about 40% of lead is absorbed through the respiratory tract. After lead enters the human body and is a...
