Abstract

High Colored kraft bleaching effluent is one of the main constrains in pulp and paper industry due to its dissloved lignin derivatives. The degradation of lignin in pulp and paper mill effluent is mainly caused by white-rot fungi. This paper showed that the treatment with KS-62 fungus significantly reduced the color and chemical oxygen demand in the effluent. The amounts of Mn ions in the wastewater would play roles in the induction and activity of MnP (Managanese peroxidase). Extracellular MnP was isolated from the fungus KS-62. The treatment with the MnP had the most effective decolorizatiion in the wastewater treatment using nutrients mediu.
