In this work, the ability of Pleurotus spp.: P. sajor-caju; P. platypus and P. citrinopileatus to treat pulp and paper mill effluent on a laboratory and pilot scale were studied. On the laboratory scale treatment, P. sajor-caju decolorized the effluent by 66.7% on day 6 of incubation. Inorganic chloride liberated by P. sajor-caju was 230.9% (814.0 mg/dl) and the COD was reduced by 61.3% (1302.0 mg/dl) on day 10 of treatment. In the pilot scale treatment maximum decolorization was obtained by P. sajor-caju (60.1%) on day 6 of the incubation. Inorganic chloride content was increased by 524.0 mg/dl (113.0%) and the COD was reduced by 1442.0 mg/dl (57.2%) by P. sajor-caju on day 7 of incubation. These results revealed that the treatment of pulp and paper mill effluent by P. sajor-caju proved as better candidate for the purpose than P. platypus and P. citrinopileatus.
