AI Technical Summary

Problems solved by technology

There are also many reports on the method of degrading bisphenol A by biological methods, but the current research on biodegradation is limited to the degradation of bacteria and some fungi screened in nature, but the degradation of bisphenol A by such strains generally requires a relatively long process. It takes a long time, and the degradation efficiency in 1 to 3 months is only about 20% to 40%, and the efficiency is relatively low

Embodiment Construction

[0032] The technical solution of the present invention will be described in further detail below in conjunction with a preferred embodiment, but the present invention is not limited to the following embodiment.

[0033] (1) Select Lactobacillus brevis as the experimental bacterial classification, and select suitable Lactobacillus brevis medium and culture conditions in a manner known to those skilled in the art, then inoculate by 0.2% amount, cultivate 24 hours as one generation, and cultivate two Substitute activation culture ends.

[0034](2) Prepare 90% (volume ratio) ethanol with sterile water for dissolving, and add bisphenol A standard substance to prepare a bisphenol A ethanol solution with a concentration of 12ppm, then take an appropriate amount of bisphenol A solution and mix it with commercially available In the yogurt (Yili brand flavored yogurt, production date November 05, 2010, production batch number 20101105 / 040103:12:57c), the yogurt containing bisphenol A 60...

Abstract

The invention relates to an application of food-grade microbiological probiotics in degradation of bisphenol A. The probiotics contain any one or more of lactobacillus helveticus, lactobacillus reuteri, lactobacillus brevis, lactobacillus delbrueckii subsp. bulgaricus, lactobacillus casei and bacillus subitilis natto. Furthermore, the probiotics preferably adopt lactobacillus brevis. The invention has the advantages that by adopting a food-grade probiotic strain for degrading bisphenol A which has an estrogen effect and is transferred into food from packing materials, the degradation cycle isshort, the degradation efficiency is high, and products are safe. The invention has obvious benefits in the aspect of food safety, and can provide a new way for degrading bisphenol A.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to the application of food-grade microbial probiotic degrading strains and the like in degrading bisphenol A in packaging materials or environmental pollutants. Background technique [0002] Bisphenol A is an "endocrine disrupting chemical" (Endocrine Disrupting Chemicals, ECD) found in food packaging materials, which has certain estrogenic properties. Bisphenol A, referred to as BPA, is mainly used in the manufacture of polymer materials such as polycarbonate (abbreviated as PC). Many everyday consumer products such as food wrappers, baby bottles, etc. may contain BPA. Bisphenol A will be precipitated into food during the heating process, which will interfere with the normal hormone secretion function of the human body, stimulate the secretion of human estrogen, and inhibit the secretion of androgen. If it is ingested in large quantities for a long time, it may cause cardiovascular ...
