“…The ascomycete, A. niger, and two basidiomycetes, P. placenta, and P. chrysosporium CDBBh-298, were obtained from the Cinvestav Culture Collection, and T. atroviride was isolated from a natural wetland that has been impacted by municipal water discharges on the central coast of Veracruz, Mexico [17]. Stock cultures were maintained on potato dextrose agar (PDA) at 4 • C. Ascomycete fungi inoculum preparation and bioscorodite production were performed in a modified Wunder mineral medium [18] that consisted of dextrose, 10 g; polypeptone, 1 g; (NH 4 ) 2 SO 4 , 1 g; MgSO 4 •7H 2 O, 0.5 g; KH 2 PO 4 , 0.875 g; K 2 HPO 4 , 0.125 g; CaCl 2 •2H 2 O, 0.1 g; NaCl, 0.1 g; MnSO 4 •H 2 O, 0.02 g; FeSO 4 •7H 2 O, 0.001 g; and distilled water, 1 L. Basidiomycete fungi inoculum preparation was performed in a Sivakumar medium [19] that contained dextrose, 20 g; yeast extract, 2.5 g; KH 2 PO 4 , 1 g; (NH 4 ) 2 SO 4 , 0.05 g; MgSO 4 , 0.5 g; CaCl 2 , 0.1 g; FeSO 4 , 0.01 g; MnSO 4 , 0.001 g; ZnSO 4 , 0.001 g; CuSO 4 , 0.002 g; and distilled water, 1 L.…”
