Over the past two decades, the use of microbes to remove pollutants from contaminated air streams has become a widely accepted and efficient alternative to the classical physical and chemical treatment technologies. This book focuses on biotechnological alternatives, looking at both the optimization of bioreactors and the development of cleaner biofuels. It is the first reference work to give a broad overview of bioprocesses for the mitigation of air pollution. Essential reading for researchers and students in environmental engineering, biotechnology, and applied microbiology, and industrial and governmental researchers.
