The reaction products formed during the decolorization of the sulfophthalocyanine textile dyes Reactive blue 15 (RB15) and Reactive blue 38 (RB38) by the white‐rot fungus Bjerkandera adusta were analyzed by high‐performance liquid chromatography with diode array detection and with liquid chromatography–electrospray ionization–tandem mass spectrometry. Sulfophthalimides (SPI; 3 and 4) were identified as major metabolites by comparison with synthesized reference compounds. SPI was formed from both dyes in fungal cultures and by incubation with its purified manganese peroxidase and lignin peroxidase. Quantitative assessment of the SPI formed from RB15 accounted for approximately 60% of the theoretical amount.
