摘要	The microbial community composition is crucial for metal extraction from solid waste by bioleaching. However, bioreactor output of bioleachant with a diverse microbial population is a great challenge due to the different growth conditions of each species. This study reports an immobilized bioreactor for the cultivation of mesophilic consortia. The optimal conditions for iron oxidation were pH 1.5, dilution of 0.382 h(-1), the temperature of 30 degrees C, and 12 g/L ferrous iron. The coexistence relationship of Acidithiobacillus ferrooxidans, Acidithiobacillus ferrivorans, and Acidiphilium spp. was relatively stable in a wider range of conditions. Further kinetics investigation showed that ferrous iron oxidation fitted well with the substrate free inhibition model of Michaelis-Menten equation below 12 g/L ferrous iron, indicating that the immobilized bioreactor culturing mesophilic consortia slowed down the inhibition process caused by the substrate and end-product. These key features would enable bioreactor design more efficient during industrial applications of bioleaching.
