Abstract
Heavy metal contamination has become a world concern with the rapid industrialization and urbanization process. In this study, a mesophile consortium including Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum ferriphilum was applied in metals’ bioleaching with the assistance of isolated acid-tolerant microorganisms Rhodotorula and Aspergillus niger. The results showed that the bioleaching was totally inhibited in non-batch method system for the alkalinity and buffering capacity of the sediment. The inhibition on bioleaching can be effectively relieved with the batch method adopted. Dissolved organic matter hampered the substrate utilization and prolonged the bioleaching process. The toxic effect of dissolved organic matter to acidophile can be reduced by the isolated heterotrophic microorganism. A. thiooxidans was the dominant species in the early bioleaching stage, while the ratio of ferrous oxidation bacteria increased in the later stage. The introduction of heterotrophic microorganism to the system contributed to form a suitable ecological niche of each species. In the batch method adopted and heterotrophic microorganism inoculated system, the bioleaching efficiency of Mn, Cu, Zn and Cd reached 94, 90.9, 94.74 and 84.2 %, respectively. The main fractions of heavy metals after bioleaching are comparatively stable speciation. Heavy metals were reduced both in total content and bioavailability.
