Résumé / Abstract

Biomass of natural origin has been accepted as an alternative economical bioremediation agent for metal removal. The present study investigates the removal of gold(III) from dilute solutions utilising a purified fungal culture of Phoma sp. Optimal conditions in batch studies with biomass and gold concentrations of 3 mg/mL and 1 mg/L respectively, at pH 5, demonstrated a removal of 90% of gold(III) from solution at 25°C. Electron microscopy indicated that adsorption and/or absorption sites for gold by the fungi were not colonised. The presence of gold in the fungi was confirmed by Energy Dispersive X-ray (EDX) spectroscopy analysis.
