This second edition of a bestselling textbook offers an instructive and comprehensive overview of our current knowledge of biocatalysis and enzyme technology. The book now contains about 40% more printed content. Three chapters are completely new, while the others have been thoroughly updated, and a section with problems and solutions as well as new case studies have been added. Following an introduction to the history of enzyme applications, the text goes on to cover in depth enzyme mechanisms and kinetics, production, recovery, characterization and design by protein engineering. The authors treat a broad range of applications of soluble and immobilized biocatalysts, including wholecell systems, the use of non-aqueous reaction systems, applications in organic synthesis, bioreactor design and reaction engineering. Methods to estimate the sustainability, important internet resources and their evaluation, and legislation concerning the use of biocatalysts are also covered.

This book was written with the purpose of providing a sound basis for the design of enzymatic reactions based on kinetic principles, but also to give an updated vision of the potentials and limitations of biocatalysis, especially with respect to recent app- cations in processes of organic synthesis. The ?rst ?ve chapters are structured in the form of a textbook, going from the basic principles of enzyme structure and fu- tion to reactor design for homogeneous systems with soluble enzymes and hete- geneous systems with immobilized enzymes. The last chapter of the book is divided into six sections that represent illustrative case studies of biocatalytic processes of industrial relevance or potential, written by experts in the respective ?elds. We sincerely hope that this book will represent an element in the toolbox of gr- uate students in applied biology and chemical and biochemical engineering and also of undergraduate students with formal training in organic chemistry, biochemistry, thermodynamics and chemical reaction kinetics. Beyond that, the book pretends also to illustrate the potential of biocatalytic processes with case studies in the ?eld of organic synthesis, which we hope will be of interest for the academia and prof- sionals involved in R&D&I. If some of our young readers are encouraged to engage or persevere in their work in biocatalysis this will certainly be our more precious reward.

The aim of food processing is to produce food that is palatable and tastes good, extend its shelf-life, increase the variety, and maintain the nutritional and healthcare quality of food. To achieve favorable processing conditions and for the safety of the food to be consumed, use of food grade microbial enzymes or microbes (being the natural biocatalysts) is imperative. This book discusses the uses of enzymes in conventional and non-conventional food and beverage processing as well as in dairy processing, brewing, bakery and wine making. Apart from conventional uses, the development of bioprocessing tools and techniques have significantly expanded the potential for extensive application of enzymes such as in production of bioactive peptides, oligosaccharides and lipids, flavor and colorants. Some of these developments include extended use of the biocatalysts (as immobilized/encapsulated enzymes), microbes (both natural and genetically modified) as sources for bulk enzymes, solid state fermentation technology for enzyme production. Extremophiles and marine microorganisms are another source of food grade enzymes. The book throws light on potential applications of microbial enzymes to expand the base of food processing industries.

Keeping in view the well-established place of enzymes in the field of biotechnology and the recent development in biotech industries, this comprehensive and well-written textbook presents the fundamental concepts of enzyme technology, emphasizing the practical and economic aspects of enzyme usage. Beginning with an overview of enzymes giving insights into the physicochemical properties, classifications, sources, mechanisms and characteristics of enzymes, the text discusses the enzyme kinetics in detail. It furnishes a great deal of information on potential of enzymes for their commercial exploitation. The text then goes on to describe the biotechnical significance of enzymes with their applications in the fields of food and pharmaceutical industries. The text is supported by a large number of solved examples and illustrative diagrams. Primarily designed for undergraduate and postgraduate students of biotechnology and biochemical engineering, the book will also be useful to professionals, researchers and entrepreneurs. KEY FEATURES: Written in an easy-to-understand style. Provides simple, clear and authoritative guide to the principles and scope of enzymes in biotechnology. Includes chapter-end review questions based on recently appeared university question papers.

Nanomaterials for Biocatalysis explains the fundamental design concepts and emerging applications of nanoscale biocatalysts, such as bioconversions, bioelectronics, biosensors, biocomputing and therapeutic applications. Nano-biocatalysts refers to the incorporation of enzymes into nanomaterials. These enzyme-enhanced nanocarriers have many advantages, including low mass transfer limitation, high enzyme capacity, better stabilization, and the formation of single-enzyme nanoparticles. Smart nanocontainers have been developed for the smart release of their embedded active substances. These smart releases can be obtained by using smart coatings as their outer nanoshells. In addition, these nanocontainers could protect the enzymes from chemical or metabolic alterations on their delivering pathways towards the target. This is an important reference source for materials scientists and chemical engineers who want to know more about how nanomaterials are being used for biocatalysis applications. - Explains the major fabrication techniques and applications of nanobiocatalysts - Shows how nanobiocatalysts are used in a variety of environmental and biomedical sectors - Assesses the major challenges associated with the widespread manufacture of nanobiocatalysts

The main subject of the "Ill. Rotenburger Fermentation Symposium" is enzyme technology. Enzyme technology could be simply defined as the scientific study of proteinaceous catalysts derived from living organisms and the application of the knowledge to solve specific problems. The scope of the application of enzyme technology ranges from medical to industrial uses and in the future even living organisms as a source of enzymes may be replaced by fully synthetic enzymes - "synzymes". Although enzyme technology still remains a particular field of biotechnology, the extremely rapid rate of expansion and the enormous increase in the diversifica tion of all aspects of enzyme technology during the immediate past has created a certain tendency to separate biotechnology and enzyme technology from each other. Certainly, those areas of biotechnology characterized by astounding advances are enzyme technology, bioreactor development and genetic manipula tion as related to biotechnological processes. However, a glance at many of the common problems of biotechnology and enzyme technology such as diffusion barriers, reactor design, mass transport, substrate or product inhibition pheno mena and the effect of physical-chemical parameters on process kinetics reveals that these two fields are inseparable with respect to research and application.

The integration of enzymes in food processing is well known, and dedicated research is continually being pursued to address the global food crisis. This book provides a broad, up-to-date overview of the enzymes used in food technology. It discusses microbial, plant and animal enzymes in the context of their applications in the food sector; process of immobilization; thermal and operational stability; increased product specificity and specific activity; enzyme engineering; implementation of high-throughput techniques; screening of relatively unexplored environments; and development of more efficient enzymes. Offering a comprehensive reference resource on the most progressive field of food technology, this book is of interest to professionals, scientists and academics in the food and biotech industries.

This book covers various method of extending the postharvest life of fruits and vegetables viz, storage, packaging, canning, chemical & low temperatures preservation, irradiation, fermentation & waste management.
