Municipal solid waste (MSW) leachate management has become an important issue worldwide. The present study evaluated the potential of indigenous fungi for biosorption of Cd2+ from leachate. Three isolates Trichoderma harzianum, Aspergillus niger and Aspergillus flavus were selected based on their ability to exclude the Cd2+ at the preliminary stage. Among these, Trichoderma harzianum was found to be an excellent fungus for cadmium absorption. The highest biosorption rate for Cd2+ was achieved under the conditions: temperature 45 degrees C (64.87%), pH 6.0 (64.78%) and spore concentration [10(5) cfu ml(-1)] (64.41%). The obtained data indicated that the developed fungal consortium is very efficient and effective for cadmium removal (72.41%), thereby demonstrating that it is a promising solution for removing toxic metals from MSW leachate.
