Dehalogenation - Microbial Processes and Environmental Applications
Max M. Häggblom and Ingeborg D. Bossert
Kluwer Academic Publishers
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 and these compounds are integral to a variety of industrial
applications. Although organohalide compounds are typically considered to be
anthropogenic industrial compounds, these 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.
Hardbound 520 pp ISBN 9781402074066
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 d
ehalogenation 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
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.
