Recent studies by L. Ouerdane and co-authors add new data to agricultural and food chemistry findings.

According to a study from Ottawa, Canada, "This paper reports, for the first time, a quantitative replacement of methionine (Met) by selenomethionine (SeMet) at >98% substitution, with up to 4940 mu g of SeMet/g of yeast obtained for the entire protein pool of a wild-type yeast grown on a SeMet-containing medium. The incorporation of selenium in yeast proteins, in the form of selenomethionine, and the influence of various organic and inorganic Se and S sources present in the media were monitored during the growth of a wild-type Saccharomyces cerevisiae, which allowed the optimization of the composition of a fully defined synthetic growth medium that ensured maximum SeMet …
