Growth kinetics of Thiobacillus ferrooxidans at high iron concentration

Through changing the initial Fe2+ concentration,the condition of metabolism during the growth of Thiobacillus ferrooxidans was studied.Based on the model of Monod function inhibited by products,the growth kinetics equation of Thiobacillus ferrooxidans at high iron concentration was built up.The results of the experiment showed that with increasing iron concentration,the function of substrate inhibition increased,and the Ks value increased.The correlation coefficient between the simulated and experimental specific growth rates was 0.97,which showed that the kinetics equation could well describe the growth of Thiobacillus ferrooxidans at high initial iron concentration.
