White-rot fungus, Schizopora paradoxa did not produce Mn-peroxidase and glucose oxidase without manganese. But, in high concentration of manganese (40 ppm), the activities of both enzymes were higher than those in basal concentration of manganese (11.15 ppm). Unlike the activities of the enzymes, mycelial mass was the same level as the control culture (11.15 ppm manganese) through out the culture period, depending on the concentration of manganese. The same experiments were carried out for the effect of copper and veratryl alcohol added to the culture. The results were not consistent dependent on the concentration of copper and veratryl alcohol, respectively. The involvement of cAMP in the correlative production of MNP and GOX was investigated. In this study, addition of atropine to the culture resulted in a concomitant inhibition of production of MNP and GOX, depending on the concentration of inhibitor added.
