Application of Various Enzymes in Waste Treatment

Abstract

The implementation of increasingly stringent standards for the discharge of wastes on to the environment has necessitated the need for the development of alternative waste treatment processes. A review of research directed toward developing enzymatic treatment systems for solid, liquid and hazardous wastes are presented. A large number of enzymes from a variety of deferent plants and microorganisms have been reported to play an important role in an array of waste treatment applications. Enzyme can act on specific recalcitrant pollutants to remove them by precipitation or transformation to other products. They also can change the characteristics of a given waste to render it more amenable to treatment or aid in converting waste material to value- added products. Before the full potential of enzymes may be realized, it is recommended that a number of issues be addressed in future research endeavors including the identification and characterization of reaction by products, the disposure of reaction products and reduction of the cost of enzymatic treatment.
