Abstract: In this study, the removal of color, chemical oxygen demand (COD) and aromatic group from one of the azo dyes, Remazol Yellow RR Gran, had been carried out by using one of the white rot fungi, Phanerochaete chrysosporium. Experimental studies were performed in growth media containing different amounts of dye and glucose. Color measurements were done at 436 nm wavelength using spectrophotometer, while aromatic group measurements were done at 280 nm wavelength using UV/Visible spectrophotometer. As a result of this study, the values of the removable color concentration were determined as 10 mgl^-1 and lower. The optimum medium glucose concentration was determined to be 2 gl^-1 during color removal processes, aromatic group measurements were done in samples in the UV region at 280 nm wavelength. As a result of the measurements, it was shown that certain amount of aromatic group remained in the model wastewater at the end of the process.
