| Popis: | Three different strains of Thiobacillus ferooxidans were grown in aqueous ferrous sulfate solutions at 30.5°C and at pH 2.0 in a bioreactor. Their specific growth rate followed Monod kinetics. Their maximum specific growth rate (μm) was between 0.138 and 0.148 h−1 and their saturation constant (Ks) was in the range from 0.338 to 0.479 g Fe2+/L. Comparing our data with other data from the literature, we concluded that the kinetics of ferrous iron oxidation is independent of the strain used. A good approximation of the growth kinetics on ferrous iron of Thiobacillus ferrooxidans between 20 and 32°C and pH 2.0–2.5 is obtained by using μm = 0.14 h−1 K s = 0.4 g Fe2+/L |
