Enzymes are biocatalysts provided by cells and are used in most metabolic methods. Most enzymes are consisting of proteins containing tertiary amino acid which bind to co enzyme or metal ions. Enzymes are accelerating biochemical processes by some mechanisms to chemical catalysts e.g metals, metal oxides and metal ions. Enzymes can be very effective under conditions e.g (temperature, atmospheric pressure and PH). Many enzymes have hydrolyzing, oxidizing and reducing characters. Enzymatic reactions always provide less side effects reactions and fewer waste by products. That is why microbial Enzymes can give an effective and environmental safe alternatives as metabolic inorganic chemical catalysts which can be used in all over pharmaceutical industrial processes. Enzymes are used in waste water treatment. Treatment technologies depend on physico-chemical approaches in wastewater treatment plants which require skills, high operation costs (in terms of high energy and chemical demand). Wastewater treatment is operated to protect the quality of limited freshwater resources, which are most times the final discharge points of effluents, and also, to promote the reusability of expended clean water; amounts of hazardous aromatic byproducts are still generated [3, 4]. The observation shows that wastewater treatment plants, though liable to remove microcontaminants such as heavy metals, and to a far lesser extent, aromatic contaminants, were originally structured for the removal of solid wastes, ecofriendly organic matter and eutrophication stimulants from wastewater, thereby reducing eutrophicating pollution loads; the micropollutants may only be moderately affected by the chemical, physical and biological interactions within the treatment plants.
