Summary White rot fungi Daldenia concentrica, Lepiota sp and Trametes serialis isolated from the Western Ghats region of Tamil Nadu, India were used to treat pulp and paper industry effluents on a laboratory scale and in
1980; Eriksson et al. 1980). They have proved role ideal organisms for decolourization as well as for the reduction of adsorb-able organic halides (AOX) and the chemical oxygen demand (COD). The pulp and paper industry is one of the major industries in India causing water pollution. The manufacture of paper yields a significant quantity of waste-water. It is estimated that 273–450 m3 of water is required to produce 1 ton of paper and about 60– 300 m3 of wastewater is discharged (Subramanium 1976; Thompson et al.
Inorganic chloride liberated by Pleurotus sajor caju was 230.9% and chemical oxygen demand (COD) was reduced by 61.3% on 10 day treatment. In pilot scale treatment maximum decolourization was obtained by Pleurotus sajor caju 60.1% on 6 day of incubation. Inorganic chloride was increased by 524.0 mg/l and the COD was reduced by 1442.0mg/l (57.2%) by Pleurotus sajor caju on day 7 of incubation (Ragunathan et al. 2004). Trametes versicolor on the fourth day of treatment showed a maximum decolourization of 63.9% in laboratory scale, Inorganic chloride at a concentration of 765mg/l, was liberated by Fomes lividus on the 10th day. The Chemical oxygen demand was also reduced to 1984mg/l by Fomes lividus. On the pilot scale, a maximum decolourization of 68% was obtained with the 6 day incubation by Trametes versicolor, inorganic chloride 475mg/l (103%) was liberated on the 7th day by Trametes versicolor and the COD was reduced by 1984 mg/l by Fomes lividus.(Savant et al. 2006) Daedaleopsis sp and Phaneochaete chrysosporium exhibited the highest ability to decolourize waste water by 52% and 86% respectively, COD was reduced by 59-71% and 66-83%.(Prasongsuk et al. 2009). The treatment of paper mill effluent in laboratory scale with Thelephora sp. a, maximum decolourization of 43.1% was observed on 4th day treatment. Inorganic chloride at the concentration of 751mg/l was liberated 10th day. The
