摘要：

Aspergillus niger was grown in an industrial gold mining solution containing cyano-metal complexes. Gold, silver, copper, iron and zinc were accumulated, and the major mechanism of metal uptake involved metal precipitation on the cell surface. This could be achieved by the extensive application of instrumental analyses combined to the study of the chemical composition of the solutions, before and after contact with the fungus.
