Microbial bio-transformations of the essential trace element selenium are now recognized to occur among a wide variety of microorganisms. These transformations are used to convert this element into its assimilated form of selenocysteine, which is at the active center of a number of key enzymes, and to produce selenium nanoparticles, quantum dots, metal selenides, and methylated selenium species that are indispensable for biotechnological and bioremediation applications. The focus of this review is to present the state-of-the-art of all aspects of the investigations into the bacterial transformations of selenium species, and to consider the characterization and biotechnological uses of these transformations and their products.
微生物对痕量必需元素硒的生物转化作用现在已经在各种各样的微生物中得到了证实。这些转化作用被用来将该元素转化为其可同化的形式——硒代半胱氨酸，后者是许多关键酶的活性中心，并产生用于生物技术和生物修复应用的硒纳米粒子、量子点、金属硒化物和甲基化硒物种。这篇综述的重点是介绍细菌对硒物种转化的各个方面的最新研究状况，并考虑这些转化及其产物的特性和生物技术用途。
