[Iron accumulation by saccharomycete yeasts growing on media with an elevated iron content]

In the absence of the artificial complexons of iron the intracellular iron content in yeast Saccharomyces cerevisiae are determined by the concentration of ions Fe(II) in medium. As iron is accumulated by yeast mainly in threevalency state the principal internal factor determining the intracellular iron content with existing concentration of Fe(II) in medium can be supposed to be redaction-oxidation state of yeast cell.
