Reaction Characteristic and Bleaching Process of Peroxidase

Abstract

The demand for environmentally friendly fiber processing and cleaning formulations prompted us to study the heat resistance, solvent resistance, pH characteristics, and the activation of peroxidases from various sources. Peroxidase has a broad substrate specificity. In a wide pH range, peroxidase was found to react with various hydrogen donor. The rate of reaction with hydrogen donors were found to be influenced by the oxidation potential of the hydrogen donor. Peroxidases from dif ferent sources were found to exhibit dif ferent stabilities and reaction characteristics. Rice full peroxidase showed excellent resistance towards heat, organic solvent, and hydrogen peroxide. The reaction mechanisms of horseradish peroxidase and rice full peroxidase were studied. Since the peroxidase reaction can be controlled by the reaction conditions, these conditions were proposed to suit the specific application.

Highly Active Peroxidase (Prx34) Derived from Moss, Physcomitrium patens, Is Produced as a Soluble Form in Escherichia coli

“…Comparison of these enzymes, including point mutations, may provide valuable information about tolerance and recovery mechanisms. Peroxidases are used in polymer synthesis, washing, and waste treatment processes, ,,, and rPrx34 represents a candidate peroxidase that can be used in these and various other industrial applications.…”

“…Thus, peroxidases from other sources have been studied. For example, a peroxidase discovered in rice is more effective at degrading azo dyes than HRP, whereas a peroxidase from palm displays high stability under conditions of high temperature, various pH values, and in organic solvents. − Extraction, recovery, and purification of peroxidases from raw sources and plant material are challenging. Moreover, isolating native peroxidases from plants is usually inefficient and can significantly impact the environment.…”
