摘　　要：硒是人体必需的微量元素,具有抗氧化、抗肿瘤和增强免疫功能等作用。乳酸菌被广泛认为是一种合适的富硒载体,能够将无机硒转化为有机硒和单质硒,从而提高硒的生物利用率和吸收率。该文综述了富硒乳酸菌的富硒机理,详细阐述了乳酸菌转化无机硒的过程以及涉及的化学物质。此外,该文还探讨了硒化产物在微生物细胞不同结构中的分布和特性,以及添加硒对菌株生长及其营养价值的影响,旨在为富硒乳酸菌的进一步开发和应用提供理论依据。Selenium(Se)is an essential trace element for the human body,which has functions such as antioxidant,antitumor,and enhancing immune.Lactic acid bacteria are widely recognized as a suitable carrier that can accumulate and covert Se from inorganic to organic and elemental forms,thereby improving the bioavailability and absorption of selenium.This article summarizes the mechanism of selenium enrichment in selenium-enriched lactic acid bacteria,how lactic acid bacteria convert inorganic selenium,and the chemicals involved in the process.The article also explores the distribution and characteristics of selenized products in different structures of microbial cells,as well as the effects of selenization on the growth and nutritional value of the strain,with the aim of providing a theoretical basis for the further development and application of selenium-enriched lactic acid bacteria.
