The completion of the Human Genome Project and the rapid progress in cell bi- ogy and biochemical engineering, are major forces driving the steady increase of approved biotech products, especially biopharmaceuticals, in the market. Today mammalian cell products (“products from cells”), primarily monoclonals, cytokines, recombinant glycoproteins, and, increasingly, vaccines, dominate the biopharmaceutical industry. Moreover, a small number of products consisting of in vitro cultivated cells (“cells as product”) for regenerative medicine have also been introduced in the market. Their efficient production requires comprehensive knowledge of biological as well as biochemical mammalian cell culture fundamentals (e.g., cell characteristics and metabolism, cell line establishment, culture medium optimization) and related engineering principles (e.g., bioreactor design, process scale-up and optimization). In addition, new developments focusing on cell line development, animal-free c- ture media, disposables and the implications of changing processes (multi-purpo- facilities) have to be taken into account. While a number of excellent books treating the basic methods and applications of mammalian cell culture technology have been published, only little attention has been afforded to their engineering aspects. The aim of this book is to make a contribution to closing this gap; it particularly focuses on the interactions between biological and biochemical and engineering principles in processes derived from cell cultures. It is not intended to give a c- prehensive overview of the literature. This has been done extensively elsewhere.
During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology. In 1950 very little was known of the chemical constitution of biological systems, the manner in which information was trans mitted from one organism to another, or the extent to which the chemical basis of life is unified. The picture today is dramatically different. We have an almost bewildering variety of information detailing many different aspects of life at the molecular level. These great advances have brought with them seme breath-taking insights into the molecular mechanisms used by nature for rep licating, distributing and modifying biological information. We have learned a great deal about the chemical and physical nature of the macromolecular nucleic acids and proteins, and the manner in which carbohydrates, lipids and smaller molecules work together to provide the molecular setting of living sys tems. It might be said that these few decades have replaced a near vacuum of information with a very large surplus. It is in the context of this flood of information that this series of monographs on molecular biology has been organized. The idea is to bring together in one place, between the covers of one book, a concise assessment of the state of the subject in a well-defined field. This will enable the reader to get a sense of historical perspective-what is known about the field today-and a description of the frontiers of research where our knowledge is increasing steadily.
1995, 1997a; NOlting, 1996). This new method allows fast processes that would normally be hidden in kinetic studies to be revealed. Of course, the range of applicability of fast kinetic methods is far wider than that presented. Thus, everybody working in the fields of fast chemical reactions and physical changes, such as conformational isomerizations, enzyme kinetics and enzyme mechanisms, might see the book as a useful introduction. The framework that is provided for the readers is the notion that the quantitation of kinetic rate constants and the visualization of protein structures along the folding pathway will lead to an understanding of function and mechanism and will aid the understanding of important biological processes and disease states through detailed mechanistic knowledge. Numerous figures provide useful information not easily found elsewhere, and the book includes copious references to original research papers, relevant reviews and monographs. My work at Cambridge University and the Medical Research Council was supported by a European Union Human Capital and Mobility Fellowship and a Medical Research Council Fellowship. I gratefully acknowledge Prof. Dr. Alan R. Fersht for the interest in our work on fast folding reactions. NMR measurements on peptides of barstar were done by Dr. Jose L. Neira and Dr. Andres S. Soler Gonzalez. The work at the University of Illinois at Urbana-Champaign was supported by NIH grant GM31756. Prof. Dr. Steven G. Sligar is particularly acknowledged for his support of acoustic relaxation experiments and many fruitful discussions.
The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.
The aim of electron probe microanalysis of biological systems is to identify, localize, and quantify elements, mass, and water in cells and tissues. The method is based on the idea that all electrons and photons emerging from an electron beam irradiated specimen contain information on its structure and composition. In particular, energy spectroscopy of X-rays and electrons after interaction of the electron beam with the specimen is used for this purpose. However, the application of this method in biology and medicine has to overcome three specific problems: 1. The principle constituent of most cell samples is water. Since liquid water is not compatible with vacuum conditions in the electron microscope, specimens have to be prepared without disturbing the other components, in parti cular diffusible ions (elements). 2. Electron probe microanaly sis provides physical data on either dry specimens or fully hydrated, frozen specimens. This data usually has to be con verted into quantitative data meaningful to the cell biologist or physiologist. 3. Cells and tissues are not static but dynamic systems. Thus, for example, microanalysis of physiolo gical processes requires sampling techniques which are adapted to address specific biological or medical questions. During recent years, remarkable progress has been made to overcome these problems. Cryopreparation, image analysis, and electron energy loss spectroscopy are key areas which have solved some problems and offer promise for future improvements.
The first edition of this book was very well received by the various groups (lecturers, students, researchers and industrialists) interested in the scientific and techno logical aspects of cheese. The initial printing was sold out faster than anticipated and created an opportunity to revise and extend the book. The second edition retains all 21 subjects from the first edition, generally revised by the same authors and in some cases expanded considerably. In addition, 10 new chapters have been added: Cheese: Methods of chemical analysis; Biochemistry of cheese ripening; Water activity and the composition of cheese; Growth and survival of pathogenic and other undesirable microorganisms in cheese; Mem brane processes in cheese technology, in Volume 1 and North-European varieties; Cheeses of the former USSR; Mozzarella and Pizza cheese; Acid-coagulated cheeses and Cheeses from sheep's and goats' milk in Volume 2. These new chapters were included mainly to fill perceived deficiencies in the first edition. The book provides an in-depth coverage of the principal scientific and techno logical aspects of cheese. While it is intended primarily for lecturers, senior students and researchers, production management and quality control personnel should find it to be a very valuable reference book. Although cheese production has become increasingly scientific in recent years, the quality of the final product is still not totally predictable. It is not claimed that this book will provide all the answers for the cheese scientist/technologist but it does provide the most com prehensive compendium of scientific knowledge on cheese available.
Most researchers agree that biological confocal microscopy was jump-started by the confocal design first published by White and Amos in 1985 in the Journal of Cell Biology. As a result, this remains a relatively young field. Yet the use of the technique has grown phenomenally since those early efforts, with new users joining the ranks daily. The publication of Basic Confocal Microscopy reflects the burgeoning need to train new students, technologists, and faculty wishing to use confocal microscopy in their research. A direct outgrowth of the authors’ five-day intensive course in the subject begun in 2005, this book covers the basics and includes all the information required to design, implement, and interpret the results of, biological experiments based on confocal microscopy. Concise yet comprehensive, the volume begins by covering the core issues of fluorescence, specimen preparation and labeling, before moving on to address the analog-to-digital conversion of specimen data gathered using confocal microscopy. Subsequent chapters detail the practicalities of operating confocal microscopes, providing all the information necessary to begin practicing confocal microscopy as well as optimizing the material obtained. The final block of chapters examine 3-dimensional analysis and the reconstruction of data sets, outline some of the ethical considerations in confocal imaging, and then supply a number of resources that the authors have found useful in their own work. Once readers have mastered the information this book presents, the resources found in its pages will be an excellent guide to continued learning about the more advanced forms of confocal microscopy.
Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en forced in food production. At the same time, there is an increasing demand for high qual ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the area of plant biotechnology and bioengineering has allowed manipulation of genes' !lnd/or insertion of new genes, thus production of trans genic plants. Starting from the introduction of agronomic traits, particularly stress resis tance to diverse environmental factors, process and sensory characteristics, food quality and production of novel varieties of plant-based products through genetic engineering, biotechnology is changing the,;agriculture and the concept of production of plant-ba~~d raw materials. Increasing attention is being paid on research for production of plants !pat can provide a wide array of food and non-food products. Perhaps the first non-food pro,d uct that plant biotechnology would achieve is production of large scale custom-designed industrial oils, but the list of chemicals is long, ranging" from oils and specific triacyl glycerols to biopolymers, enzymes, blood components, amo~g others.

Tissue engineering is an exciting new field at the interface of engineering and - ology that uses implanted cells, scaffolds, DNA, proteins, protein fragments, and inductive molecules to repair or replace injured or diseased tissues and organs. Tremendous progress in biological and biomaterial aspects of this field have been accomplished to date, and several engineered tissues are now being used clinically. However, tissue engineers face major challenges in repairing or repl- ing tissues that serve a predominantly biomechanical function. To meet this challenge, the United States National Committee on Biomech- ics in 1998 adopted a new paradigm termed functional tissue engineering (FTE) to emphasize the importance of biomechanical considerations in the design and - velopment of cell and matrix-based implants for soft and hard tissue repair. Functional tissue engineering represents a relevant and exciting new discipline in the field of tissue engineering. Since many tissues, such as those of the muscu- skeletal, cardiovascular, and dental systems, are accustomed to being mecha- cally challenged, tissue-engineered constructs used to replace these tissues after injury or disease must certainly do the same. Of course, tissue engineers must also attempt to return normal biological activity in order for the construct to truly - tegrate with the surrounding tissues. Thus, the term functional can have many meanings, such as restoration of metabolic function. The primary focus of this text is on the role of biomechanical function in tissue engineering.
The esculent Lycopersicon esculentum, long thought to be poisonous, has become a major U. S. food crop and source of vitamins and minerals, thanks largely to genetic modification and new production technology Rick (1978) Tomato (Lycopersicon esculentum Mill. ) is one of the most important solana ceous vegetable crops grown worldwide under outdoor and indoor conditions. It has become an important commercial crop so far as the area, production, industrial values and its contribution to human nutrition is concerned. During the past few decades tremendous developments have contributed to the knowledge and understanding of various areas of genetics, breeding and biotechnology and voluminous literature has been generated. The purpose of preparing this monograph is to give a comprehensive up-to-date treatment to the various aspects of genetic improvement of tomato. The emphasis has been placed on cytology, classical and molecular genetics, reproductive biology, germplasm resources, hybrid seed production, use of wild taxa, selection/ breeding methods, breeding for abiotic and biotic stresses, processing and quality breeding, improvement for mechanical harvesting, and biotechnology: tissue culture, protoplast fusion, and genetic transformation. These topics are presented in 22 different chapters. However, a few aspects have been discussed in more than one chapter. For example, seed production is treated in chapters 1, 4 and 8; molecular biology/genetic engineering in chapters 3 and 22 and heterosis in chapters 8 and 16.
