Plasmid-Mediated Biodegradative Fate of Monohalogenated Biphenyls in Facultatively Anaerobic Sediments
Interactions between bacterial populations and environmental pollutants which result in the partial or complete biodegradation of the pollutant are of multifaceted importance. Studying these interactions can provide useful information for predicting the persistence of pollutants and needs for discharge and release regulations. Additional information can be obtained to quantify and assess pollutant exposure levels from both ecological and environmental health perspectives. Such studies may also be a source of new bacterial isolates containing genetic information potentially useful for wastewater treatment and pollution abatement. Finally, qualitative and quantitative descriptions of these interactions may provide insights into microbial evolution and natural selection, ranging from the population level to the molecular level. The objective of this report is to review some fundamental concepts and problems related to the microbial ecology of pollutant biodegradation in anaerobic and facultatively anaerobic sediments, and to describe in greater detail current research on the biodegradation of monohalogenated biphenyls (as models for polychlorinated biphenyls) by sediment bacterial populations.
