中文摘要	The filamentous fungi XLA and XLC isolated from Cd-contaminated soil were identified morphologically and phylogenetically as Paecilomyces lilacinus and Mucoromycote sp., respectively. The minimum inhibitory concentrations (MICs) of Cd2+, Co2+, Cu2+, Zn2+, Cr3+ and Cr6+ in minimum mineral (MM) medium agar plates were 29,786, 2945, 9425, 5080, 1785 and 204 mgL(-1) for XLA and 11,240, 884, 9100, 2540, 3060 and 51 mgL(-1) for XLC, respectively. Favorable biosorption conditions for adsorption of Cd2+ by the tested fungi were investigated. Efficient performances of the biosorbents were described using Langmuir isotherm model, and the predicted maximum biosorption capacities for Cd2+ were 77.61 mgg(-1) of XLA and 79.67 mgg(-1)of XLC. Experiments on desorption potential of biosorbents validated their efficacy at a large scale. Results showed that XLA obtained a desorption rate of 84.7% by 2% EDTA and XLC gained a desorption rate of 78.9% by 0.1 M HCl. Analysis by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) and X-ray photoelectron spectroscopy (XPS) suggested that groups of C-N, COO- for XLA and C-N, CH2 and phosphate for XLC were the dominant binding sites for Cd2+ biosorption. Our results indicated that the fungus XLA, rather than XLC, could potentially be used as an inexpensive, eco-friendly and effective bioremediation agent for the removal of Cd2+ from wastewater.\
