“…Specifically, the use of plant peroxidases in removal of phenolic pollutants from aqueous solution is well documented [19,20]. It has been demonstrated that horseradish peroxidase (HRP) can catalyze free-radical formation, followed by spontaneous polymerization of a variety of aromatic compounds, including phenol [21][22][23][24], chlorophenols [13,25] and other substituted phenols [26], in the presence of hydrogen peroxide (H 2 O 2 ). Furthermore, HRP is also known to have the ability to degrade aromatic azo compounds in the presence of H 2 O 2 and to precipitate industrially important azo dyes [15,16,27,28].…”

This study evaluates the potential of the enzyme horseradish peroxidase in the decolorization of one common industrial azo dye, naphthol blue black. Studies are carried out to understand the process parameters such as pH, temperature and reaction time. The enzymatic decolorization of the dye was examined by UV-Vis spectrophotometer and LC-MS measurements. Temperature and pH conditions were optimized for obtaining high azo-dye decolorization. Azo-dye removal at a pH range 4-6 was found to be the highest for all temperatures. After 5 minutes of treatment, the color removal of dye was ca. 80-90%. The LC-MS and spectrophotometric analyses indicated that the decolorization of the azo dye with enzyme was due to the reduction of the azo bonds. This study verifies the viability of the use of the horseradish peroxidase in the decolorization of naphthol blue black.

“…Considerable efforts have aimed at optimizing the HRP-catalyzed removal of phenols from aqueous solutions. Improvements in the useful life of the enzyme, and thereby a reduction in treatment cost, have been accomplished through: selection of an appropriate reactor configuration (Nicell et al, 1993b); the use of additives such as polyethylene glycol to protect the enzyme from premature inactivation (Nakamoto and Machida, 1992); the addition of absorbents such as talc which protect the enzyme from inhibition by reaction products (Arseguel and Baboulène, 1994); and the immobilization of the enzyme on solid supports (Bodzek et al, 1994). In particular, the advantages of immobilization for enzymes can include the preservation of enzyme activity (Coppella et al, 1990), the potential for continuous flow treatment (Caldwell and Raushel, 1991) and the possibility of enzyme reuse (Munnecke, 1977).…”

Enzymatic processes fall between the two traditional categories of chemical and biological treatment systems since they involve chemical reactions based on the action of biological catalysts. A variety of enzymes from plants and microorganisms have been reported to play important roles in an array of waste treatment applications. Before the full potential of enzymes may be realized, a number of significant issues remain to be addressed. These include: development of low-cost sources of enzymes in quantities that are required at the industrial scale; demonstration of the feasibility of utilizing the enzymes efficiently under the conditions encountered during wastewater treatment; characterization of reaction products and assessment of their impact on downstream processes or on the environment into which they are released; and identification of methods for the disposal of solid residues, among others.

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.
