Immobilization of Cells

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.
