166 ABSTRACT Bioremediation strategies have potential for eliminating or reducing the xenobiotics from environment. One such strategy would to use enzymes to degrade the hazardous chemical compound from environment. Micro- organisms are now known to be the principal agents, which can clean and modify the complex lipophilic organic molecules, once considered recalcitrant, to simple water soluble products. They first attack these organic chemicals by the enzymatic apparatus acquired during the course of enrichment, when they are exposed to these specific or structurally related compounds. Presence of these contaminants in the environment either induces or depresses the enzymatic function of microorganisms. This capability largely depends upon the selective microbial community as well as on the structural and functional groups of toxic compounds. These water soluble intermediates are usually attacked by primary or secondary groups of organisms to form inorganic end products, resulting in complete biodegradation of hazardous chemicals. Bioremediation is the use of living organisms, primarily microorganisms, to degrade the environmental contaminants into less toxic forms. Now day s relative new technologies are present which increase the bioremediation process faster and more fruitful in short time period. Such technologies act on either on three components of bioremediation which are important for this process to occur. These three levels are explained in this paper.
