Decolorization of recalcitrant dyes by a multicopper oxidase produced by Iodidimonas sp. Q-1 with iodide as a novel inorganic natural redox mediator.

A multicopper oxidase (IOX) produced by Iodidimonas sp. Q-1 has high catalytic efficiency for iodide (I) oxidation to form molecular iodine (I). In this study, the potential capacity of IOX for decolorization of recalcitrant dyes was determined.
