| 摘 要： | 本文报道了酵母在同化无机硒为有机硒的过程中，培养基的种类、亚硒酸钠浓度以及蛋氨酸浓度与生成的硒酵母中的硒蛋氨酸量的某些规律。实验结果表明：硒酵母中硒蛋氨酸的量与培养基的种类有关，随培养基中亚硒酸钠浓度的增加而增加，而随蛋氨酸浓度的增加而减少。提出了一个准确测定生物物质中硒代氰基酸的分析方法。

| Abstract: | In the process of assimilation of inorganic selenium by yeast to the organic-selenium, some rules on the relation of the kinds of culture medium, concentration of sodium selenite and methionine to the total selenium and selenomethionine content in the yeast formed have been found; and a new, accurate procedure--modified acid hydrolysis-ion exchange chromatography for determining the content of seleno-amino acid in biological materials has been established. |
