Selection of Suitable Synthetic Medium for As(III) Biosorption by Aspergillus niger X₃₀₀

An experimental study was carried out to select a suitable synthetic medium for growth and As(III) biosorption by an As(III) resistant strain Aspergillus niger X₃₀₀. For this purpose different medium components were optimized one by one. A synthetic medium composed of glucose, 12%; (NH₄)SO₄, 0.8%; K₂HPO₄, 0.01%; KH₂PO₄, 0.01%; CaCl₂. 2H₂O, 0.03%; NaCl, 0.02%; MgSO₄.7H₂O, 0.03 μg/ml; MnSO₄.4H₂O, 0.02 μg/ml; FeSO₄.7H₂O, 0.02 μg/ml and thiamine-HCl, 0.02μg/ml was strongly recommended for this purpose.
