Abstract

A variety of modern biotechnical approaches are available to assist in optimizing and controlling bioremediation processes. These approaches are broad-ranging, and may include genetic engineering to improve biodegradative performance, maintenance of the environment, and process monitoring and control. In addition to direct genetic engineering strategies, molecular diagnostic and monitoring technology using DNA gene probing methods and new quantitative mRNA analytical procedures allows direct analysis of degradative capacity, activity, and response underin situ conditions. Applications of these molecular approaches in process developments for trichloroethylene (TCE), polychlorinated biphenyls (PCB), and polynuclear aromatic hydrocarbons (PAH) bio-oxidation in soils, aquifer sediments, and ground-water treatment reactors have been demonstrated. Molecular genetic technologies permit not only the development of new processes for bioremediation, but also new process monitoring, control strategies, and molecular optimization paradigms that take full advantage of vast and diverse abilities of microorganisms to destroy problem chemicals.
