| Abstract: | Determination of content of organic selenium, selenocystine(SeCys) and selenomethionine(SeMet) in cultured selenium yeasts is reported. The inorganic selenium and organic selenium were seperated with dialysis bag, and the content of organic selenium in selenium yeasts was determined by catalytic spectrophotometry; the content of selenocystine and selenomethionine in selenium yeasts were determined by amino acid analyzer. |
