Textile dyeing wastewater involving resistant dyestuffs contaminate rivers because of their color and the production of hazardous or carcinogenic intermediates, which must be removed before being released into streams. The ligninolytic enzymes have many uses, including the elimination of dyestuffs from industrial wastewater. In this study, the Lignin Peroxidase enzyme was used to eliminate synthetic solutions of Naphthol Blue Black (NBB) and Remazol Brilliant Blue R (RBBR) dyestuffs at pH 5.0 and 30 °C. In addition, the effect of 1-hydroxybenzotriazole (HOBt), a redox mediator, on dye removal at different concentrations was investigated. Once a redox mediator was added to the LiP enzyme, the percentage of RBBR dye eliminated increased from 10% to 26% after 24 hours. On the first day after adding HOBt to the LiP enzyme, the percentage of NBB dye eliminated increased from 5% to 89%. The effect of HOBt was significantly greater in the NBB than in the RBBR. The redox mediator-added Lignin Peroxidase enzyme decolorized the NBB dye more efficiently than the RBBR dye.

In recent times, enzymatic approaches have been used in treatment of colored wastewater/industrial effluents. Peroxidases are very useful in removal of recalcitrant toxic compounds or transforming them into innocuous products. Although much attention has been paid in the utilization of biocatalysts in several fields, their involvement in solving the environmental problems has gained support. Enzymes in soluble states have limitations of catalytic ability and stability. As the complexity of the effluents increases, the ability of the enzymes to execute its catalytic potential decreases. Therefore, one of the approaches to improve stability, catalytic ability, reusability and shelf life of enzymes is by immobilization. Work in the area of enzyme technology has provided significant clues that facilitate using enzymes optimally at large scale by cross-linking, entrapping and immobilizing. The current article presents an insight into the use of peroxidases immobilized on several different supports for the dye color removal of synthetic dyes as well as several different contaminants.

Recently, enzymatic treatment using peroxidases in removal of aromatic compounds has gained importance. In this study pointed gourd peroxidase was salt fractionated and direct immobilization of these proteins on diethylaminoethyl cellulose for oxidation of phenol and α-naphthol has been investigated. The activated diethylaminoethyl cellulose was quite effective in high yield immobilization of peroxidases from pointed gourd and it could bind ~576 units per g of the matrix. Immobilized pointed gourd peroxidase on this anion exchanger showed very high effectiveness factor 'Ɛ' as 0.91 with an activity yield of 91%. Immobilized PGP (I-PGP) as compared to soluble counterparts (s-PGP) were more effective and removed 79%, 88% and 54% oxidation of phenol and α-naphthol by 75%, 81% and 61% at 30, 40 and 50°C respectively, with a treatment time of 140 min. In the absence CdCl2 s-PGP as well as I-PGP exhibited upto 93% of oxidation of these compounds; whereas the presence of CdCl2 of negatively affected the removal of phenol and α-naphthol. The reactor worked well continuously for over one month for effectively oxidizing/ removing phenol and α-naphthol by 54% and 61% respectively. Thus, such immobilized enzyme systems in reactor have a great future and could be exploited for treating organic pollutants present in industrial effluents.
