Enzyme Extraction From Plant Waste Materials: Implementation in Decolorizing of Industrial Effluents

Wastewaters from the textile industry contain various contaminants. Among them, anthraqui-none dyes are considered to be highly toxic to the aquatic biota. Enzymatic treatment of wastewater from textile industry has drawn a great deal of interest since it is eco-friendly and a cost effective technology, comparing to chemical and physical decolorization methods. In addition to its environ-mental benefits, enzymes can be isolated from plant waste materials making them more alluring for utilization. One of plenty enzymes potentially used in purification of wastewater is peroxidase. It could be readily used for degradation of anthraquinone dyes. In this study, extraction of peroxidase from the following waste materials is performed: apple peel, banana peel, potato peel, and soybean hull. Next, enzyme activity is measured and from the results obtained, the most suitable waste material source is selected. Afterwards, the dye concentration is varied for the purpose of determining the optimal one for degradation.
