Extraction, purification and characterization of peroxidase from Vitis vinifera wastes
The proper consumption of plant wastes could not only provide a possible source of natural products, but it also is an environmental friendly research. The aim of this study was to use grape wastes as a source of peroxidase.  In practice, one isoenzyme of peroxidase (POD1) was partially purified from Vitis vinifera wastes, the plant which is widely harvested in Iran. The activity of this novel peroxidase was determined using guaiacol as its substrate. The new peroxidase was partially purified and its kinetic parameters determined. The values of Km and Vmax of peroxidase for guaiacol were 83.2 mM and 0.35 M/min respectively. Optimum pH and temperature were determined for guaiacol to be 6.2 and 60°C respectively. According to SDS-PAGE results, the molecular weight of isozymes was 38-40 KD. The results indicate that agricultural leftovers from Vitis vinifera are a considerable source for a peroxidase with reliable kinetic behaviors.
