Abstract A process for recovering metals from aqueous media con- taining metal in solution, and especially from industrial waste water. The process includes the steps of contacting the aqueous medium with fungus for a period of time suf- ficient to allow the fungus to extract metal in a water- insoluble form from the solution. The metal may then be recovered from the fungus. Fungi of the species Clado- sporium, Penicillium, Trichoderma, Black Mycelium and Aureobasidium, have been found to be particularly useful in the process of the present invention. The process is useful, both as a water purification-process and as a metals recovery process.
