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

A least-squares error minimization approach was adopted to assess ferric ion diffusion coefficient of Fricke-agarose gels. Ferric ion diffusion process was modeled as a Gaussian-shaped degradation kernel operating on an initial concentration distribution. Diffusion coefficient was iteratively determined by minimizing
