This study examined whether iron accumulated in ferritin-producing recombinant microbes is bioavailable to rats with iron deficiency. Rats induced with iron deficiency were treated with iron preparations of ferrous ammonium sulfate, horse spleen ferritin, control yeast, and ferritin-producing recombinant yeast...
