Decolourisation Capabilities of Ligninolytic Enzymes Produced by Marasmius cladophyllus UMAS MS8 on Remazol Brilliant Blue R and Other Azo Dyes

Figure 6

In vitro decolourisation of 0.2 g L⁻¹ (a) RBBR dye, (b) Orange G, and (c) Congo red using ammonium sulphate precipitated crude enzyme. Solid line: control spectrum of the tested dye with heat inactivated enzyme. Dashed line represents the spectrum of the tested dye after 19 hours of being treated with enzyme containing 450 U L⁻¹ of Lac activity. Arrow indicates the decrease of the spectrum at the maximum absorption wavelength of the respective dyes.
