Growth kinetic and removal of heavy metal by Trichoderma brevicompactum QYCD-6 with (A) in absence of metal; (B) at 50 mg L⁻¹ of Cu; (C) at 50 mg L⁻¹ of Cr; (D) at 50 mg L⁻¹ of Cd; (E) at 50 mg L⁻¹ of Pb; (F) at 50 mg L⁻¹ of Zn; (G) at 50 mg L⁻¹ of Multi Metal Mix. The fungus was grown in composite media except that of 50 mg L⁻¹ of Pb (in PD medium).
