A white-rot fungus Phanerochaete chrysosporium effectively removes COD, color, and TOCl from bleach plant effluents due to its enzymatic ligninolytic system. The effects of glucose, a required cosubstrate, and Tween 80, a surfactant, on the degradation of chlorolignins, and thereby, the COD, color, TOCl are studied. A glucose concentration exceeding 2,000 mg/1 during the fungal treatment does not adversely effect the decolorization rate. However, it does effect the rate of degradation and dechlorination of chlorolignins. Tween 80 appears to have an effect on color removal, but not on degradation and dechlorination. However, the addition of 0.1% Tween 80 during fungal treatment prolongs the fungal lifetime.
