Volume 3 of Bioreaction Engineering covers the general principles and techniques of bioprocess monitoring and their application for various bioprocesses. Methods based on the author's long standing experience working with various bioprocesses are applied within the book. In particular, the cultivation of Baker's yeast; production of fusion protein with recombinant E. Coli, alkaline serine protease production with Bacillus licheniformis; production of penicillin V with Penicillin chrysogenum; Cephalosporin C with Acremonium chrysogenum and tetracycline with Streptomyces aureofaciens are considered. This book deals with the monitoring of batch and perfusion cultivations of animal cells and production of monoclonal antibodies with hybridoma cells, Antithrombin III with BHK and CHO cells and ß -galactosidase with insect cells. The topics covered include: Bioprocess monitoring techniques Cultivation of Saccharomyces cerevisiae Production of Fusion Protein with Recombinanat E. coli Alkaline Protease Production with Bacillus licheniformis Antibiotica Production by Fungi and Streptomycetes Continuous Production of Primary Metabolites with Suspended and Immobilized Microorganisms Cultivation of Animal Cells and Production of Proteins Anaerobic Waste Water Treatment Fast Process Monitoring Techniques Image Analysis of Cells and Cell Aggregates Evaluation of Experimental Data to the Calculation of Metabolite Flux in Microorganisms and Animal Cells Signal Evaluation, Automation and Expert Systems for Process Monitoring Bioprocess Monitoring is invaluable for process engineers, analytical chemists and researchers in biotechnological, pharmaceutical, environmnental and chemical industries.

Solvent Extraction in Biotechnology deals with the reco- very and purification of primary and secondary metabolites by solvent extraction. In the first part the reaction engineering principles: definitions, thermodynamic fundamentals, and system models, the kinetics of mass transfer between two phases without and with chemical reaction as well as extraction equipment, which are important for downstream processing in biotechnology, are considered in detail. The special part of the book describes the recovery of low-molecular metabolites: alcohols, acids and antibiotics with organic solvents, carrier-modifier-solvent systems, supercritical gases as well as with liquid membrane techniques. Several practical examples are given for the recovery of different metabolites as well as for the calculation of the extraction processes necessary for equipment design. Besides solvent extraction, novel separation techniques with liquid membrane, microemulsion and reversed micelles are also presented. This book will introduce the biochemical engineer and process engineer to the recovery of products from complex cultivation broths by modern techniques of solvent extraction and help them with process design.

Stresses which arise in bioreactors can influence process performance considerably. Recent molecular biological investigations indicate that stress caused by fluid dynamical effects and extreme values of process variables and toxic substances cause similar responses in the cells. These molecular fundamentals, as well as quantitative evaluation of fluid dynamical stresses and, their effects on microorganisms, animal and plant cells and proteins are treated in this volume.

The state of the art of the bioengineering aspects of the morphology of microorganisms and their relationship to process performance are described in this volume. Materials and methods of the digital image analysis and mathematical modeling of hyphal elongation, branching and pellet formation as well as their application to various fungi and actinomycetes during the production of antibiotics and enzymes are presented.
