Abstract

The issue of environmental pollution by industrial waste, agricultural chemicals, synthetic plastics and oil products like petroleum hydrocarbons has become very serious worldwide because of its resistance to damage and toxicity. Traditional physicochemical cleaning methods often have problems of high cost of operation, ineffective removal, and causes secondary environmental pollution. For these reasons, bioremediation has become a viable alternative being environmentally friendly and sustainable and therefore finds application in the detoxification of polluted environments by using biological systems. Enzyme based bioremediation has gained much strong attention among other bioremediation strategies due to its high specificity, effectiveness and the capacity to convert complex and resistant pollutants into less harmful or environmentally friendly products. The role of the major microbial enzymes; oxidoreductases, peroxidases, hydrolases, oxygenases, dehalogenases as well as plastic-degrading enzymes are carefully analyzed in terms of their mechanism and environmental impacts.
