Lactic acid bacteria are a class of probiotics widely used in food,medical and cosmetics industry.As a essential trace element for human,selenium(Se)plays a critical role in metabolism and immunoregulation.ln recent decades,Se-enriched lactic acid bacteria attract extensive attention due to their outstanding antioxidant,anti inflammatory,antitumor activities and the ability to transform inorganic selenium into organic form,which is beneficial to human absorption.However,further studies about metabolic pathways of Se by LAB are needed;meanwhile,it is necessary to test and evaluate the toxicities and side effects of Se-enriched probiotics and their fermented foods.In this paper,the oxidation state of selenium,the effects on the growth of LAB by selenium,the transformation of organic selenium by LAB,bioactivities of Se-enriched LAB and Se-enriched functional foods were summarized.
