- 摘要: This volume, authored by leading experts in the field, provides a current perspective on how both natural and synthetic organohalides are formed and degraded, and how these processes are incorporated into a global halogen cycle. The list of organohalides that can be utilized by microbes continues to increase dramatically, as do the number of dehalogenating microorganisms that have been identified and characterized. A critical step in the degradation of organohalides is cleavage of the carbon-halogen bond, and microorganisms have evolved a variety of metabolic strategies for dehalogenation. The chapters provide a global perspective on the diversity of dehalogenating microorganisms, explore their ecology, biochemistry and genetics, and review the range of biologically-mediated dehalogenation mechanisms. Many of the problematic organohalides, such as pesticides, chlorofluorocarbons, chlorinated solvents, polychlorinated dibenzo-p-dioxins and polychlorinated biphenyls, are covered in detail. The book provides a comprehensive overview of fate of these compounds in the environment, practical applications in the laboratory and the field, and strategies for the development of bioremediation technologies for organohalide-contaminated sites. Detailed information on biodegradation and biotransformation mechanisms for a variety of organohalides and on the microorganisms mediating these processes has greatly increased our understanding of the cycling and fate of these unique and widespread compounds in our environment. The book will serve as a comprehensive resource on the processes and applications of microbial degradation of halogenated organic compounds.

Halogenated organic compounds constitute one of the largest groups of environmental chemicals. The industrial production of new halogenated organic compounds has increased throughout the last century peaking in the 1960s, and continuing in widespread use today. Organohalides are integral to a variety of industrial applications, including use as solvents, degreasing agents, biocides, pharmaceuticals, plasticizers, hydraulic and heat transfer fluids, and intermediates for chemical synthesis, to name a few. It is important to recognize the beneficial aspects of halogenated organic compounds, as well as their potentially deleterious impact on the environment and health. Recognition ofthe adverse environmental effects ofmanytypes oforganohalide compounds has led to efforts to reduce or eliminate the most problematic ones. Although organohalide compounds are typically considered to be anthropogenic industrial compounds, they have their counterpart in several thousands of natural biogenic and geogenic organohalides, representing most classes of organic chemicals. Natural sources account for a significant portion of the global organohalogen budget. This volume authored by recognized experts in the field provides a current perspective on how both natural and synthetic organohalides are formed and degraded, and how these processes are incorporated into a global halogen cycle. The focus is on microbial processes, since these play a major role both in the production and degradation, i. e. , cycling of halogenated organic compounds inthe environment. This book is organized into five parts. Part I, Introduction, provides a global perspective on the issues of organohalides and their fate in the environment.
