Figure 4: Microscopic observation of the effect of Cd (0.5 mM) and pyrene (10 ppm) on the mycelial morphology of P. chrysosporium. Micrographs of samples used in Figure 3 were recorded by transferring them onto glass slides under light microscope at 10X magnification. The treatments were as follows: 4A: Control; 4B: Cadmium; 4C: Pyrene; 4D: Cd+Pyrene.
