Computer-munching-microbes: metal leaching from electronic scrap by bacteria and fungi

摘要

We applied microbiological processes to mobilize metals from electronic waste materials.Bacteria (Thiobacillus thiooxidans,T. ferrooxidans) and fungi (Aspergillus niger,Penicillium simplicissimum) were grown in the presnece of electronic scrap.The formation of inorganic and organic acids caused the mobilization of metlas.Initial experiments showed that above a concentration of 1
