In this research, a kinetic model to assess its fitness to the batch cultivation of Aspergillus niger for the bioleaching
process of iron removal from kaolin was developed. A simple model was proposed using the logistic equation for
growth, and the Luedeking-Piret equations for iron removal, acid formation and sucrose consumption. We compared the
performance of our model against that obtained by the empirically experimental data. The model appeared to provide a
reasonable description for each parameter during the growth phase. The experimental results also suggest that the iron
removal from kaolin was growth-associated to some extent, but with increase in iron concentration in solution, the
growth of cell is limited.
