"The selected dyes (Indigo Carmine, RBBR, Congo red, Malachite green and Bromophenol Blue) have never been tested before with Myrothecium sp. IMER1 on solid medium (Figure S1). First, Indigo Carmine was completely decolorized, as revealed by the >78 mm diameter of the decolorized zone after six days. Decolorization of RBBR was less extensive with a decolorized zone diameter of between 63 to 70 mm. Second, partial decolorization was obtained for Congo red and Malachite green. Finally, little decolorization was observed for Bromophenol Blue. Myrothecium sp. IMER1 showed different potentials to decolorize five different dyes which belong to four classifications. The class of the dye which defines its structure is influential in deciding the extent to which dye is decolorized. Wong and Yu observed that anthraquinone dye was rametes versicolor accase substrate while azo and indigo dyes were not the substrates of laccase.
