The ability to predict the behavior of fermentation systems enhances the possibility of optimizing their performance. Mathematical equations of model systems represent a tool for this and the most recent advances in computer hardware and software have made the approach more effective than previous simplistic attempts. The current knowledge of biochemical microbial pathways and the experience in optimization of chemical reactors combined with extremely powerful and accessible computers, loaded with easy to use software and mathematical routines, are changing the way processes are being developed and operated.

This book has been written for all those who work with microbial cultures, providing a useful, quick and contemporary re-education for practitioners and students alike, breaking through interdisciplinary barriers. Biologists, engineers and biochemists will benefit from the methods of microbial process description and optimization based on mathematical equations. The basic techniques of modeling the bio-system are summarized in Part I. The useful concept of mass balancing is introduced in Part II for those who are not used to this simple and very useful engineering tool. An extensive and descriptive case study of a selected fermentation bio-process in Part III elucidates further the concepts of very pragmatic mathematical modeling of bioreactor systems.

The volume outlines how to simply develop mathematical models of microbial systems and demonstrates their power to: guide and minimize the experimental work; check the consistency of experimental results; predict the behavior of the bio-system and analyze biocatalytic processes; diagnose the anomalies in the microbial culture behavior and optimize the performance of bioreactors.

This volume addresses the key topics: nonaqueous enzymology in general and protein design for organic solvents in particular, and enzymatic synthesis of carbon-carbon bonds, novel oligosaccharides, and modified steroids. It is a valuable source to experienced as well as potential users of enzymes.

Contributors from European and US universities and corporations review recent developments in the integration of downstream processing and bioconversion, describing their experience with many separation technologies, including some still in the experimental stage. The topics include the construction

This book, intended for advanced graduate students of metallurgy, explains what happens in the critical period between extractive metallurgy and solidification and subsequent processing. An important point the book stresses is that the principles are the same in the treatment of various different metals. Someone concerned with the purification of one metal may learn from results and experiences gained on other metals and alloys. The specifics of metals such as iron and steel, aluminium, and copper are discussed in examples and in problems at the end of each chapter. The book is self-contained and covers the basic thermodynamics and fluid mechanics required.

To optimize separations, membranes are imprinted with various molecules. The theory and mechanism of the separation as well as strategies for imprinting are explained in this book.

This book gives an introduction to molecular biophysics. It starts from material properties at equilibrium related to polymers, dielectrics and membranes. Electronic spectra are developed for the understanding of elementary dynamic processes in photosynthesis including proton transfer and dynamics of molecular motors. Since the molecular structures of functional groups of bio-systems were resolved, it has become feasible to develop a theory based on the quantum theory and statistical physics with emphasis on the specifics of the high complexity of bio-systems. This introduction to molecular aspects of the field focuses on solvable models. Elementary biological processes provide as special challenge the presence of partial disorder in the structure which does not destroy the basic reproducibility of the processes. Apparently the elementary molecular processes are organized in a way to optimize the efficiency. Learning from nature by means exploring the relation between structure and function may even help to build better artificial solar cells. The reader is exposed to basic concepts in modern biophysics, such as entropic forces, phase separation, potential of mean force, electron and proton transfer, heterogeneous reactions, coherent and incoherent energy transfer as well as molecular motors. Basic knowledge in classical and Quantum mechanics, electrostatics and statistical physics is desirable. Simplified models are presented which can be solved in limited cases analytically from the guiding lines to generate the basis for a fundamental understanding of the more complex biophysical systems. Chapters close with challenging problems whose solutions are provided at the end of the book to complete the pedagogical treatment in the book. To the second edition several new chapters were added. The medium polarization is treated self-consistently using basic elements of polaron theory and more advanced nonlinear Schroedinger equations to describe the dynamics of solvation. Ion transport through a membrane was extended by the discussion of cooperative effects. Intramolecular transitions are now discussed in the new edition in much more detail, including also radiationless transitions. Very recent developments in spectroscopy are included, especially two-dimensional and hole-burning spectroscopy. The discussion of charge transfer processes was extended by including recent results of hole transfer in DNA in connection with the super-exchange mechanism. The chapter on molecular motors was rewritten to include the most recent developments of new models. The book is a useful text for students and researchers wanting to go through the mathematical derivations in the theories presented. This book attracts a group of applied mathematically oriented students and scholars to the exciting field of molecular biophysics.

In the 1980's sonochemistry was considered to be a rather restricted branch of chemistry involving the ways in which ultrasound could improve synthetic procedures, predominantly in heterogeneous systems and particularly for organometallic reactions. Within a few years the subject began to expand into other disciplines including food technology, environmental protection and the extraction of natural materials. Scientific interest grew and led to the formation of the European Society of Sonochemistry in 1990 and the launch of a new journal Ultrasonics Sonochemistry in 1994. The subject continues to develop as an exciting and multi-disciplinary science with the participation of not only chemists but also physicists, engineers and biologists. The resulting cross-fertilisation of ideas has led to the rapid growth of interdisciplinary research and provided an ideal way for young researchers to expand their knowledge and appreciation of the ways in which different sciences can interact. It expands scientific knowledge through an opening of the closed doors that sometimes restrict the more specialist sciences. The journey of exploration in sonochemistry and its expansion into new fields of science and engineering is recounted in "Sonochemistry Evolution and Expansion" written by two pioneers in the field. It is unlike other texts about sonochemistry in that it follows the chronological developments in several very different applications of sonochemistry through the research experiences of the two authors Tim Mason and Mircea Vinatoru. Designed for chemists and chemical engineers Written by two experts and practitioners in the subject Volume 1 covers the historical background and evolution of sonochemistry Volume 2 explains the wider applications and expansion of the subject VOLUME 1 Fundamentals and Evolution This volume traces the evolution of sonochemistry from the very beginning when the effects of acoustic cavitation were first reported almost as a scientific curiosity. The major developments of the subject from the 1980's are described by the authors who became active participants in the field during that period. A chapter is devoted to ultrasonically assisted extraction (UAE) which illustrates the different ways in which sonochemical technologies can be applied in both batch and flow modes leading to the development of large-scale processing. The chapter on environmental protection shows the wide range of applications of sonochemistry in this important field for both biological and chemical decontamination.
