Brazilian Archives of biology and technology, 47(2), 179-1831516-8913http://hdl.handle.net/10347/22733Physiological aspects were evaluated to determine optimal conditions for the decolorization of a synthetic dye, Poly R-478, by white-rot fungus Trametes versicolor # 52J. The decolorization experiments were carried out in semicontinuous operation during three cycles to improve the process efficiency. The best decolorization efficiencies (65% to 80%) were obtained in fungal cultures performed in nitrogen limited conditions under aerobic conditions.eng© Brazilian Archives of Biology and Technology, 2004.
