Method of bological transforming selenium using bacillus bifidus and its product

A process for bioconverting the Se by bifidobacteria features that the bifidobacteria are cultured in the Se-enriched culture medium for converting the inorganic Se to low-poison organic Se while obtaining the Se-enriched living bifidobacteria, which have the functions of improving immunity and preventing and treating cancers. 本发明公开了一种利用双歧杆菌对硒进行生物转化的方法及其产品。利用双歧杆菌对硒进行生物转化的方法，将双歧杆菌进行富硒培养，制成双歧杆菌富硒活菌制剂，旨在利用生理性双歧杆菌将培养液中的无机硒转化为低毒的菌体细胞有机硒，将二者的抗癌功能与双歧杆菌的微生态调节功能相叠加，生产出富硒双歧杆菌单菌株活菌制剂，由该方法生产出来的产品不但具有抗癌防癌功能，而且该制剂的硒载体选择双歧杆菌，此菌为人体正常生理细菌，在增进机体免疫力方面具有重要的功能。
