Microbiological Oxidation of the Waste Ferrous Sulphate

Ferrous sulphate, a waste product in titanium white production at the Chemical Plant "Police" S.A., was subjected to microbiological oxidation with Thiobacillus ferrooxidans bacteria. The kinetic parameters of the culture growth were calculated on the basis of the Monod equation. The process was found to be best described by the model of the autocatalytic 1st order reaction with respect to the ...

Ferrous Sulphate Oxidation Using Acidithiobacillus FerrooxidansCells Immobilized in Ceramic Beads

The immobilization of Acidithiobacillus ferrooxidans cells on ceramic beads as carrier is described. The effects of ferrous ion concentration and dilution on the kinetics of ferrous ion oxidation in a packed-bed bioreactor were studied. In a medium containing 13.91 g of ferrous ion per litre, the fastest oxidation rate was 4.21 g L–1 at a dilution rate of 0.8 h–1. The corresponding conversion w...

Bioavailability of Stabilized Iron (II) Sulfate in an Industrialized Fortified Infant Dessert. Studies in Rats by Means of the Prophylactic-Preventive Method

The purpose of the present work is to evaluate the iron bioavailability of stabilized iron (II) sulphate in industrialized fortified infant dessert. The prophylactic–preventive test in rats, using ferrous sulphate as the reference standard, was applied as the evaluating methodology. Thirty female Sprague–Dawley rats weaned, were randomized into three different groups (group 1: FeSO4 + IDF; grou...

Iron deficiency up-regulates iron absorption from ferrous sulphate but not ferric pyrophosphate and consequently food fortification with ferrous sulphate has relatively greater efficacy in iron-deficient individuals.

Fe absorption from water-soluble forms of Fe is inversely proportional to Fe status in humans. Whether this is true for poorly soluble Fe compounds is uncertain. Our objectives were therefore (1) to compare the up-regulation of Fe absorption at low Fe status from ferrous sulphate (FS) and ferric pyrophosphate (FPP) and (2) to compare the efficacy of FS with FPP in a fortification trial to incre...
