“…As an example, horseradish peroxidase is employed to remove phenols in the presence of H 2 O 2 from contaminated aquifers by polymerization and precipitation in porous media. 3 Moreover, a bienzymatic system made of a glucose oxidase and horseradish peroxidase immobilized on phospholipid-templated silica nanocapsules has been recently exploited as a catalyst in the reaction of 4-aminoantipyridine and phenol with in situ produced H 2 O 2 . 4 Peroxidases are also known to be effective in the degradation of dyes using hydrogen peroxide: 5 dyes recalcitrant to common chemical bleaches were successfully treated using horseradish and soybean peroxidases.…”

The peroxidase activity of wild-type yeast cytochrome c and its triple mutant K72AK73AK79A adsorbed onto kaolinite was investigated as a function of pH and temperature. Both adsorbed proteins displayed an appreciable catalytic activity, which remained constant from pH 7 to pH 10, decreased below pH 7, and showed a remarkable increase at pH values lower than 4. In the whole pH range investigated the catalytic activity of the adsorbed wild-type cytochrome c was higher than that of the mutant. Both diffuse-reflectance UV-vis and resonance Raman spectroscopies applied on solid samples were used to probe the structural features responsible for the catalytic activity of the immobilized proteins. At neutral and alkaline pH values a six-coordinate low-spin form of cytochrome c was observed, while at pH < 7 the formation of a high-spin species occurred whose population increased at decreasing pH. The orientation and exposure of the heme to the substrate-strictly dependent on adsorption-was found to affect the peroxidase activity.

A sequential injection analysis (SIA) with chemiluminescence (CL) detection system was developed for determination of total antioxidant content (TAC) in wines and beverages. The method is based on the CL reaction between luminol and hydrogen peroxide in alkaline conditions with the presence of a K3Fe(CN)6 catalyst. Antioxidants in the sample scavenged a reactive oxygen species as hydrogen peroxide and the decrease in CL intensity was observed that related to the TAC in sample. A cost-effective CL detection system with a home-made spiral configuration flow-cell was designed and constructed by inexpensive materials. The spiral chemiluminescence flow-cell was made from an opaque white polymer of polymethyl methacrylate (PMMA) or acrylic plastic. Furthermore, a light-to-voltage optical sensor was used as a low-cost alternative detector which is small and was also used for the miniaturization of instrument. Thus, the developed CL detection system is cost-effective, portable and has the ability to connect with flow-based systems. The optimum conditions of SIA-CL method were studied and the linear range for gallic acid was obtained ranging from 0.5 to 5.0 mmol L-1, the limit of detection (LOD) was 0.25 mmol L-1 and the limit of quantitation (LOQ) was 0.84 mmol L-1. The reproducibility of the method was investigated and the between day %relative standard deviation was in the range of 2.2 to 5.4%. The %recovery was between 95.8 and 105.6% and the sample throughput was 60 samples h-1. The proposed method was successfully applied for the determination of TAC in wine and beverage samples and the results were not significantly different when compare with the reference method. Therefore, the developed SIA-CL method is simple, fast, accurate and consume less reagent.
