Immobilization of Cells: 5 (Biotechnology Monographs) - Hardcover

Growth of immobilized cells can be viewed as an alternative to growth of free cells in many instances. In others, immobilization confers a precision of control over the process not possible in free growth. Immobilization of cells can sometimes be considered to be a lower cost alternative to immobilization of enzymes. In this volume, immobilization procedures based on mechanical means and bonding of various types are examined, with detailed application examples. These applications include microorganisms, plant and animal cells, sub-cellular organelles and multiple enzyme systems. Particular attention is devoted to enzyme properties in immobilized cells and the properties of the carrier. The volume should provide the reader with a comprehensive overview of the subject, together with copious references. As well as serving as a research monograph, it could be used to provide reference material for a graduate course. Special thanks are due Mrs. JENNIFER KERBY for her dedicated work in the preparation of the manuscript, and IT-CHIN HSIEH for bibliographical assistance. COLIN R. PHILLIPS Toronto, July 1988 YIU C.

This book presents a review of fundamental concepts of cell immobilization, and includes methods of immobilization, properties of immobilized cells, and areas of application. The mechanics of immobilization, kinetics of immobilized cell reactions, and approach to reactor design are discussed first, followed by the various methods of immobilization, including adsorption, covalent bonding, cross-linking, encapsulation and entrapment. The mechanical, biological and chemical properties of immobilized cells are then described, followed by application in areas such as pharmaceuticals, food products, beverages and industrial raw materials. The book presents a unified treatment of the topic and will be of value to research workers, academics and students in several interdisciplinary fields.
