The microorganisms was domesticated by adding a certain amount of lead in the soil, and three lead-tolerant strains including Pb-R-1, Pb-R-2 and Pb-H-3 accordingly originating from 300 mg/L, 750 mg/L and 900 mg/L lead medium were isolated with a series of PDA medium of different lead concentrations. Through the identification, Pb-R-2 was confirmed as Aspergillus sp., Pb-R-3 as Penicillium sp. The trials of transferring culture showed that all strains had the stable heredity of lead tolerance in different composition PDA medium.
