摘　　要：微量元素是生物有机体必需的营养元素,在维持生物体的正常代谢过程中起着重要作用。富集微量元素的功能酵母能将无机态微量元素转化为有机态微量元素,以提高其生物利用率;其自身含有丰富的营养成分,很适合作为饲料添加剂应用在畜牧业中。文中综述了几种富集微量元素的功能酵母——富硒酵母、富铁酵母、富锌酵母和富铬酵母等的生理功能及其研究概况和富集微量元素的功能酵母在饲料行业中的应用前景。Trace elements are necessary nutrients of organism. They are important to maintain the normal metabolism of organism. Yeast can transform inorganic trace elements into organic form. In addition the biological utilization rates of trace elements are improved. Yeast contains abundant nutrient components, and it can be applied as feed additive to animal industry. In this paper, the biological function, research and application prospect of several kinds of yeast enriching trace elements were reviewed, for example, selenium-enriched yeast, iron-enriched yeast, zinc-enriched yeast and chromium-enriched yeast.
