Figure 3: Effect of Cd (0.5 mM) and pyrene (10 ppm) on the mycelial morphology of P. chrysosporium as measured visually using photography 3A: Untreated control and cadmium treatment; 3B: Pyrene and Cd+pyrene treatments. The xenobiotic treatments were carried out while the cultures were growing at 37°C in an environmental shaker (180 rpm) for 72 hours. Equal volume of the fungal culture suspensions were transferred to independent petriplates and photographs were taken using Panasonic (DMC-LZ2, 6X optical zoom). Representative photographs are presented.
