LACTIC ACID BACTERIA HAVING HIGH BISPHENOL A ADSORPTION, PRAPARING METHOD OF THE SAME, MILK PRODUCTS USING THE BACTERIA AND METHOD FOR MEASURING REMOVALABILITY OF ENDOCRINE DISRUPTING CHEMICALS

摘要

A novel Lactobacillus delbruekii subsp. lactis BT lactic acid strain is provided to show high absorption capability on bisphenol A, thereby capable of controlling the toxicity of the bisphenol A. The Lactobacillus delbruekii subsp. lactis BT shows high bisphenol A absorption property and is deposited as a deposition number of KCTC 10799BP. The milk products having lactic acid bacteria as a starter is characterized in that the Lactobacillus delbruekii subsp. lactis BT is used as the starter to produce the milk products. The method for preparing the Lactobacillus delbruekii subsp. lactis BT comprises the steps of: (a) forming a concentration gradient culture medium of 100-300 microgram/ml of bisphenol A; (b) streaking the Lactobacillus delbruekii subsp. lactis BT in the medium of the step(a) to culture it; and (c) isolating a single colony type strain having the resistance on the bisphenol A growing in the medium of the step(b).
