The residual lignin in unbleached kraft pulp is commonly removed to afford a fully bleached pulp through a multi-stage bleaching process consisting of chlorination and alkaline-extraction stages. The effluent from such a bleaching process is of growing environmental concern because it shows a dark brown color and contains numerous chlorinated organic substances. Moreover, this effluent is not easily recycled within a mill recovery system because of the potential corrosion problems created by its high chlorine content. White-rot fungi have even heavily modified lignin such as kraft lignin and atoms demonstrated that kraft bleaching effluent can be rot fungi, in particular, Trametes versicolor and this review lecture, the possibility of the application of kraft effluents will be discussed.
