摘　　要： 对极大(S.maxima)和钝顶(S.platensis)两种螺旋藻在接种后第5d和第6d两天内添加Na2SeO3(累计加硒浓度分别为600、800和1000mg/L),获得了有机硒含量分别为474.37、562.93、645.98μg/g(DW)的S.maxima和352.68、501.85、1198.15μg/g(DW)的S.platensis。分别测定了螺旋藻藻体及培养液中的无机硒、有机硒和总硒含量,分析了无机Se(IV)经螺旋藻吸收、代谢后的分布状况。 Na2SeO3 was added to two kinds of Spirulina, S. maxima and S. platensis. On the fifth and sixth days after inoculation, the cumulating concentration of Selenium reached 600, 800 and 1000mg/L respectively. S. maxima containing organic selenium 474.37, 562.93, 645.98μg/g （DW） and S. platensis containing organic selenium 352.68, 501.85, 1198.15μg/g （DW） were obtained. The inorganic selenium, organic selenium and total selenium in both the Spirulina and the culture were assayed respectively. It was also studied in this paper the distribution of selenium after the absorption and metabolization of Spirulina.
