A disperse dye-removing fungus, Cunninghamella polymorpha, was isolated from soil. C. polymorpha efficiently removed an average 93% of 17 tested disperse dyes in 120 h, and 90% of C. I. Disperse Blue 60 was removed even at a high concentration of 500 mg/l. The dye removal was due to the sorption of dye to the fungal cells.
