Probing horseradish peroxidase catalyzed degradation of azo dye from tannery wastewater Concurrent reduction of iodine and oxidation of EDTA at Horseradish peroxidase (HRP) catalyzes the reduction of iodine to iodide by EDTA with pseudocatalatic degradation of H2O2 to O2 (Banerjee et al., (1986) J. Biol. Chem. 261, 10592-10597; and Banerjee (1989) J. Biol. Chem. 264, 9188-9194). The reduction of iodine (I+) is dependent on EDTA concentratio

Degradation of 2,4,6-trinitrotoluene by immobilized

This paper presents horseradish peroxidase (HRP)-catalyzed removal of 2,4,6-trinitrotoluene (TNT) by an electrochemical packed-bed flow reactor operated in a circulating batch mode with the help of in situ generated hydrogen peroxide. HRP immobilized on the reticulated vitreous carbon electrode was prepared for the cyclic voltammetry of 2,4,6-TNT. Facile Fabrication of a Novel Copper Nanozyme for Feb 23, 2021 · Probing horseradish peroxidase catalyzed degradation of azo dye from tannery wastewater Preethi Sadhanandam; Anumary Ayyappan; Ashokkumar Meiyazhagan; Thanikaivelan Palanisamy SpringerPlus ( 2013 ), 2 ( ), 341 ISSN:2193-1801 . Horseradish peroxidase catalyzed degradation of Horseradish peroxidase (HRP) is known to degrade certain recalcitrant organic compounds such as phenol and substituted phenols. Here, for the first time we have shown HRP to be effective in degrading and precipitating industrially important azo dyes. For Remazol blue, the enzyme activity was found to be far better at pH 2.5 than at neutral pH.

Mechanistic Investigations of Horseradish Peroxidase We have reported recently the degradation of carboxylated SWNTs through enzymatic catalysis with horseradish peroxidase (HRP). In this full Article, we investigated the degradation of both carboxylated and pristine SWNTs with HRP and compared these results with chemical degradation by hemin and FeCl 3. The interaction between pristine and carboxylated SWNTs with HRP was further studied by Optimization of Horseradish Peroxidase Catalytic For optimizing the reaction conditions of 2-methyl-6-ethylaniline (MEA) degradation catalyzed by horseradish peroxidase (HRP), a response surface methodology with three factors and three levels was used in this research to establish a regression model, a ternary quadratic polynomial, in order to analyze temperature, H2O2 concentration and pH effects on MEA removal efficiency.

Peroxidase-mediated degradation of perfluorooctanoic acid.

Peroxidase-mediated degradation of perfluorooctanoic acid. Colosi LM (1), Pinto RA, Huang Q, Weber WJ Jr. Author information:(1)Department of Civil and Environmental Engineering, University of Virginia, Charlottesville, Virginia 22904, USA. Concentrations of aqueous-phase perfluorooctanoic acid (PFOA), a representative perfluorinated aliphatic (PFA) compound, are shown to be reduced effectively via Peroxidasemediated degradation of perfluorooctanoic acid Dec 09, 2009 · Peroxidasemediated degradation of perfluorooctanoic acid are shown to be reduced effectively via reaction with horseradish peroxidase (HRP), hydrogen peroxide, and a phenolic cosubstrate (4methoxyphenol). This, to the best of our knowledge, is the first report to substantiate the efficacy of HRPcatalyzed reactions for The Reaction of Coumarins with Horseradish PeroxidaseAbstract. The peroxidase catalyzed oxidation of indole-3-acetate is inhibited by naturally occurring coumarins such as scopoletin. This inhibition is due to the preferential reactivity of the coumarins with the peroxidase compounds I, II, and III. In view of the possible growth regulatory role of coumarins in plants, the mechanism of oxidation of scopoletin by horse-radish peroxidase has been investigated.
