Bioremediation is regarded as a desirable means of restoration of contaminated sites. Fundamental and applied research activity is being carried out on the biodegradation of contaminants, development of engineering systems for bioremediation, and in understanding how the biological processes interact with the abiotic processes that take place in nature. This volume assesses varying aspects of bioremediation, problems encountered at field sites, and scale-ups of solutions being generated at bench scale with the objective of furthering critical developments and their utilization.
