To identify the enzymes potentially useful for decolorization of azo dyes, secretome ascomycetous fungus Myrothecium roridum IM6482 was studied by using a bottom-up proteomic approach. Among identified proteins, most promising dye removal laccase, which decolorized respectively, 66, 91, 79, and 80% Acid Blue 113 (AB 113), Red 27 (AR 27), Direct 14 (DB 14), Orange 7 (AO 7). The degradation dyes enhanced at wide range pH from 4 to 8. addition redox mediators allowed eliminating AB in concentrations up 400 mg/L simulated textile effluent. Microbial toxicity phytotoxicity tests indicated that are converted into low-toxicity metabolites. This is first insight M. secretome, its identification application select dyes. Obtained results extended knowledge concerning biodegradative potential ascomycetous, ligninolytic fungi will contribute improvement fungi.
