“…Researchers are now focusing on white rot fungi for use in bioremediation processes since these organisms have the ability to degrade a wide range of environmental pollutions (Fu and Viraraghavan, 2001;Paszczynski and Crawford, 1995;Pointing, 2001;Shah and Nerud, 2002). The decolorization can be achieved either by adsorption or oxidative degradation by the enzymes (Fu and Viraraghavan, 2001;Knapp et al, 1999). While many studies have been carried out on biodecolorization, for example, decolorization of textile dyes and their effluents using white rot fungi (Sathiya et al, 2007); biological treatment of a pulp and paper industry effluent by Fomes lividus and Trametes versicolor (Selvam et al, 2002); degradation of lignin in pulp mill wastewaters by white rot fungi on biofilm (Wu et al, 2005), no attention has been paid to the treatment of leachate by white rot fungi.…”

This study focuses on treatment of landfill leachate in column experiments by immobilized Trametes versicolor on polyurethane foam, collected from Nonthaburi landfill site, Thailand. In this study, glucose was used as a co-substrate. The effect of biomass growth on color removal was observed by immobilizing fungi on polyurethane foam. The same immobilized fungi were used for four cycles of 5 days each to find the reuse of fungi. Leachate was diluted to see the effect of organic loading on color removal. At optimum pH of 4 and in 20 days with 3 g/L of glucose, the fungi could decolorize 78 % and 63 % for 5-times dilution and concentrated leachate, respectively, using immobilized fungi after 4 days initial growth. Fungi could also reduce biological oxygen demand and chemical oxygen demand of 52 % and 42 % (with initial biological oxygen demand and chemical oxygen demand of 48,900 and 96,512 mg/L), respectively, with glucose 3 g/L in concentrate leachate and with 4 days initial immobilization of fungi on polyurethane foam. About 1-6% higher color removal was observed on day 20 with 15 days fungi immobilization initially as compared to 4 days immobilization. Higher removal efficiency was observed for the same leachate after dilution due to reduction in organic loading. Addition of co-substrate enhances significantly removal of color, biological oxygen demand and chemical oxygen demand. Chemical oxygen demand removal reached to 0.6 mg/mg of biomass with the co-substrate. Therefore, white rot fungi can be considered as potentially useful microorganisms in landfill leachate treatment.

“…Knapp et al (1995) and Revankar and Lele (2007) found that the decolorization of dye in stationary cultures was mainly due to the sorption of the dyes on the fungal mat, while no adsorption of dye on fungal mycelium was seen in agitated culture and that indicates that the dye removal by the tested fungi was attributed to dye biodegradation and/or biosorption. However one or more of these mechanisms (biosorption, biodegradation or enzymatic mineralization) could be involved in colour removal, depending on the fungus used (Coulibaly et al, 2003).…”

Six fungal species were isolated from Egyptian soil and identified as Aspergillus flavus, Aspergillus niger, Penicillium canescens, Penicillium crustosum, Penicillium sp. and Fusarium sp. and were tested for their decolorization activity of direct blue dye (DB). Aspergillus flavus and Penicillium canescens were the best active fungal species for decolorization of direct blue dye. The optimum conditions for direct blue dye decolorization by both fungi grown on Czapek's Dox liquid medium were at a concentration of 0.01% Direct blue dye, sucrose as a carbon source, NaNO3 as a nitrogen source, incubation temperature 30°C and 35°C and pH 4, 5 for both fungi respectively and incubation time for 7 days. Addition of some metals (Ca, Ni, Co) to the growth medium exhibited little effect on dye decolorization. Whereas, Cu (2+) highly inhibited dye decolorization by both fungi.

“…Adsorption of dyes to the microbial cell surface is the primary mechanism of decolourization. Absorption was found to be important mechanism that contributes to the decolourization process, possibility to initial transformation of the dye degradation [45]. Microscopic examinations showed that the fungal spores, instead of the fungal hyphae were actually absorbing the dye.…”

“…The free radical process provides some basis for the non specific nature of white-rot fungi. The free radical reactions catalyzed by the peroxidases from white-rot fungi also appear to be involved in the degradation of a variety of pollutants [26,45]. Paszczynski et al [19] reported the involvement of veratryl alcohol during the degradation of azo compounds.…”

Present review highlights the role of fungi in biodegradation/decolourization of textile dyes and effluents. Though, fungi and bacteria both are the principal decomposer of xenobiotics in the environment but fungi are superior to bacteria in dyes degradation/decolourization due to their superiority in the production of dyes degrading enzymes and as absorbent. The present study focused on the achievements and advancement on the fungal degradation/decolourization of textiles dyes and effluents by the application of potent fungal strains. The biodegradation through fungi or myco-remediation of textile dyes and effluents using potential fungi is comparatively cheap and environmentally safe process, to decompose or mineralize the hardly or less degrading compounds of synthetic dyes. Fungi play an important role to degrade/decolourize the synthetic dyes through enzymes as well as by the absorption, adsorption and accumulation of colourants from the effluents.
