Pulp and paper mill effluent contains organic, inorganic and coloring compounds which have high pH, biological oxygen demand (BOD), chemical oxygen demand (COD), total solids (TS), and phenols along with lignin. When untreated or poorly treated pulp and paper mill effluents discharged into the environment, it causes adverse effects on aquatic as well as terrestrial environments. Due to the heavy pollution load of pulp and paper mill industries, the removal of pollutants present in the effluent is very necessary for environmental safety. Thus, in this study deals with the bioremediation of pulp and paper mill effluent by the bacterial strain PLP 2 was isolated from contaminated site of pulp and paper mill industry. The isolated bacterial strain PLP 2 was effectively reduced colour (69%) and lignin (44%) after 144 h of treatment at 35℃, pH 7.5 and 120 rpm in presence of glucose (1.0%) and peptone (0.5%) as additional carbon and nitrogen source. Therefore, this study showed that the isolated bacterial strain can be useful for the effective bioremediation of pulp and paper mill effluent.
