A marked departure from other books available on the market which center on one or two specialties, Biotechnology for Environmental Engineering focuses on a combination of topics covering biology, microbiology, engineering design and unit operations in technology with a comprehensive introduction to the new technologies and emerging modeling concepts in these fields.The book begins with the fundamental of biomolecules which is discussed with introductory cell chemistry, amino acids, polypeptides and nucleic acids. The basics of microbiology related to genetics and ecology, followed by a review of the order and status of proteins are presented to give readers a better grasp of the topics. In addition, enzymes, energetics, stoichiometry as well as kinetics of microorganisms and their ecological relations are discussed in detail. The applications of different types of microorganisms to treat the mixture of pollutants are covered alongside with analyses of all types of bioreactors, including attached growth and suspension growth equipments. More importantly, the ecological aspects such as the role of biology in lagoons, lotic and wetlands are explored. The final sections of the book give a thorough coverage on various treatment systems, including all biomediation processes.With the fundamental principles presented clearly, this book can be used as a textbook of environmental biotechnology for the environmental engineering or environmental science major. It can also be used as a reference book for environmental professionals.
