%X Congo Red (CR) was decolorized and degraded by the main enzymes secreted by Schizophyllum sp. F17 which were investigated in a novel system established by our laboratory. Catabolite analysis showed that CR was decolorized and degraded effectively by Schizophyllum sp. F17. The decolorization percentage of CR reached 91.5% 48 h after mycelial pellet addition and the maximum activity of MnP, the main degradation enzyme, reached 96.1 U·L-1. Furthermore, from the UV-Vis spectrum of CR, the absorption peak at 495 nm vanished and new absorption peaks appeared in the ultraviolet region after 96 h and 192 h of decolorization. Benzidine is initially produced in the degradation process. It was isolated by HPLC and its identity was confirmed by FT-IR, mass spectrometry and NMR. The benzidine was itself degraded gradually over time.
