FIG. 5.

Correlation between the degradation of T. fusca porphyrin and peroxidase activity during the initial burst phase. Time courses for peroxidase activity of the T. fusca supernatant (left ordinate; squares) and porphyrin degradation at an absorbance (Abs) of 385 to 403 nm (right ordinate; circles). Measurements were made with 100 mM sodium or potassium phosphate buffer at pH 7.0 and 30°C.
