Figure 1a: Cadmium tolerance in Phanerochaete chrysosporium, the fungal cultures were grown at 37°C in an environmental shaker (180 rpm) for 72 hours; Cd was added at variable concentrations at the 24 hour time-point. Fungal biomass was harvested by vacuum filtration and dried to a constant weight at 80°C. Values plotted represent average of triplicates ± standard deviation.
