“…A reverse phase column, Inertsil ODS‐3 (5 μm, 4.6 mm i.d. × 15 cm), was used 15–17. The aliquots (0.3 cm 3 ) taken from the reaction solutions were immersed in hot water at 80–85°C for 5 min to deactivate tyrosinase and centrifuged at 4000 rpm for 10 min.…”

“…Therefore, enzymatic treatments have been more frequently used as an alternative procedure. In fact, oxidoreductases such as peroxidase13, 14 and tyrosinase15, 16 have been used to catalyze detoxication or transformation of bisphenol A (BPA) and its derivatives13, 14, 16 as well as alkylphenols and chlorophenols 15, 17. Tyrosinase has the catalysis to convert phenolic compounds into the corresponding quinone derivatives.…”

“…We have focused attention on enzymatic quinone oxidation in the presence of porous chitosan beads. Various phenolic compounds were removed in short reaction times through nonenzymatic quinone adsorption on chitosan beads 15–17. As described above, many studies have been reported on removal of various phenol compounds 13–17.…”

In this study, the combined use of chitosan and mushroom tyrosinase was applied to remove 1‐naphthol and 2‐naphthol from aqueous solutions. In particular, the process parameters, such as the pH value, temperature, and enzyme dose, were discussed for tyrosinase‐catalyzed quinone oxidation of 1‐naphthol. The optimum conditions of enzymatic quinone oxidation of 1‐naphthol were determined to be pH 8.0 and 40°C. Under the optimum conditions, quinone oxidation of 1‐naphthol increased with an increase in the enzyme dose. Quinone derivatives enzymatically generated were chemisorbed on chitosan bead sand. The initial velocity of enzymatic quinone oxidation increased with an increase in the amount of added chitosan beads, since unfavorable interactions between quinone derivatives and tyrosinase in the solutions were restrained by quinone adsorption. 1‐Naphthol was completely removed for 8 h by quinone adsorption on chitosan beads (0.10 cm3/cm3) at 20 U/cm3. The removal time was shortened by increasing the enzyme dose or the amount of added chitosan beads. 2‐Naphthol was also completely removed by increasing the enzyme concentration and reaction time, since enzymatic quinone oxidation of 2‐naphthol was much slower than that of 1‐naphthol. The above results reveal that the procedure constructed in this study was an effective technique to remove naphthols. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

“…Taking into account these issues, there is the need to develop a new, ecological and auto-sustainable way for the treatment of phenolic effluents. A promising process appears to be the enzymatic oxidation (Durán and Esposito 2000;Faria et al 2007), particularly by polyphenol oxidase (PPO) that is more commonly referred to as tyrosinase (Martin et al 2008;Romanovskaya et al 2009;Yamada et al 2009). Another enzyme equally efficient in the oxidation of phenols is the polyphenol peroxidase (Campeanu et al 1999), but it has the disadvantage of requiring hydrogen peroxide instead of atmospheric oxygen as a substrate (Ikehata and Nicell 2000a, b;López-Molina et al 2003).…”

This work aimed to develop a new economic enzymatic process to treat the phenolic pollutants using pure tyrosinase in stirred vessel and adopting temperature (T), pH, rotational speed (N), initial phenol (C P,o ) and enzyme (C T ) concentrations as independent variables. Experimental data of the residual phenol concentration (C P ) were used to calculate the oxidation efficiency (η), initial oxidation rate (-r o ) and time required to reach the end of reaction (t) that were selected as the responses. Under the optimal conditions (T = 45°C, pH 6.6

In this study, a combined use of biopolymer chitosan and oxidoreductase polyphenol oxidase (PPO) was applied to the removal of bisphenol A (BPA) as an endocrine disrupting chemical from aqueous solutions. The optimum conditions for the enzymatic quinone oxidation of BPA were determined to be pH 7.0 and 40 C. Quinone derivatives generated were chemisorbed on chitosan beads, and BPA was completely removed at 4-7 h. The removal time was shortened with an increase in the amount of dispersed chitosan beads or the PPO concentration. In addition, the initial velocity of quinone oxidation increased with an increase in the amount of chitosan beads. The use of chitosan in the form of porous beads was more effective than the use of chitosan in the form of solutions or powder. It was found that an important factor for this procedure was a high-specific surface area of chitosan beads and heterogeneous reaction of quinone derivatives enzymatically generated with chitosan.
