Abstract

Of the enormous number of different halogenated organic compounds that have been chemically synthesized, several have found widespread use, particularly as solvents and biocides. This use has led to their being accidentally or intentionally released into the environment, mainly to groundwater. Although there is good evidence for natural production of chlorinated organic compounds, many of the anthropogenic organic halogen compounds appear to be resistant to chemical and biological degradation and therefore persist in the environment. This chapter discusses the roels of anaerobic microorganism in the biodegradation of these compounds and focuses mainly on chlorinated compounds.
