29/7/2017, · The, decolorization, efficiencies for disperse, dyes, (red 1, orange 3 and black 1) were 51-80% within 9 days. The CBR43 could effectively, decolorize, high concentrations of, acid blue, 62 and, acid, black 172 (500-700 mg L-1). The maximum, dye decolorization, rate was obtained at 28°C, pH 5, and 150 rpm in the PDB medium.

The present investigation focuses on the decolorization of Acid Blue 62 (AB62) in EMR. AB62 was selected as the products of its oxidation by laccases are well known and they are less toxic than AB62 [26]. The process was performed using extracellular laccase from Cerrena unicolor because this biocatalyst can be produced without any inducers and its
