Metabolic engineering is a multidisciplinary field which uses techniques of genetic engineering and mathematical modeling to regulate the metabolic processes of a cell. The regulation of these genetic processes and modification of metabolic networks are used for production of specific substances. This discipline incorporates principles from computational sciences, molecular biology and chemical engineering to alter specific biochemical reactions. This book focuses on recombinant DNA technology, analytical methods and other tools to understand the applications of metabolic engineering. It is a wonderful source of reference for students, researchers and academicians working in this field.
