Biological Degradation and Bioremediation of Toxic Chemicals

The concept of bioremediation is not new - the farmer and the forester practice it in a limited way by rotating crops and replanting trees. Because unassisted natural processes cannot break down the many toxic wastes we inflict on our world, more sophisticated bioremediation techniques are imperative. This book covers the increasing use of microorganisms and microbial metabolic processes to break down such environmental poisons and clean soil and water. An ever broadening variety of bacteria, other microbes, and fungi are being discovered already living in extreme environments such as high-temperature undersea volcanic vents, highly acidic, alkaline, or salty habitats, or anaerobic situations. Fortunately, many posses metabolic pathways that can remove or destroy toxic compounds such as herbicides, insecticides, and heavy metals.In chapters written by authors on the cutting edge of investigative research, Biological Degradation and Bioremediation of Toxic Chemicals thoroughly covers the range of such organisms and the use of such pathways. Also described are genetic and molecular biological techniques to improve the ability of microorganisms to degrade harmful compounds, including the conversion of wastes into useful products. The book provides a comprehensive basis for further research, indicating future directions for biotechnological applications.
