This book offers an explanation of the specific ways that biocatalysis outperforms chemical catalysis by: utilizing ambient temperature and atmospheric pressure to minimize problems of isomerization, racemization, and epimerization; employing microbial cells and enzymes that can be immobilized and reused over many cycles; and overexpressing enzymes for greater economy and efficiency.
Das Gesamtgebiet der Biokatalyse mit allen seinen Facetten -- Mikrobiologie, Enzymologie, Molekularbiologie, Strukturbiologie, organische Chemie -- wird in diesem interdisziplinär angelegten Werk beleuchtet; insbesondere geht es um enzymatische Katalysen und Ganzzell-Katalysen. Ein Schwerpunkt liegt dabei auf der Entwicklung hochselektiver, umweltfreundlicher Prozesse zur Synthese wichtiger Verbindungsklassen.
This reference book originates from the interdisciplinary research cooperation between academia and industry. In three distinct parts, latest results from basic research on stable enzymes are explained and brought into context with possible industrial applications. Downstream processing technology as well as biocatalytic and biotechnological production processes from global players display the enormous potential of biocatalysts. Application of "extreme" reaction conditions (i.e. unconventional, such as high temperature, pressure, and pH value) - biocatalysts are normally used within a well defined process window - leads to novel synthetic effects. Both novel enzyme systems and the synthetic routes in which they can be applied are made accessible to the reader. In addition, the complementary innovative process technology under unconventional conditions is highlighted by latest examples from biotech industry.
An authoritative review of the latest developments in the chemical biology of enzymes In the first decade of the twenty-first century, enzymes and their multiple applications have played a critical role in the discovery and development of many new therapeutic agents.This book is a coordinated compilation of research expertise and current opinion uniquely focused on enzymes and their properties and applications. Compiled by editors with a combined pharmaceutical experience of over sixty years, the text provides in-depth reviews of recent developments in selective topics on biosynthesis, biocatalysis, and chemical biology of enzymes as it applies to drug discovery, development, and manufacture. The first in a multi-part series on enzymes, this volume features three sections: New Approaches to Find and Modify Enzymes describes the emerging field of metagenomics, presents the practical applications of directed evolution to enzymes and pathways, and explores approaches for the discovery and design of biocatalysts Biocatalytic Applications reviews specific applications of different reactions in producing active pharmaceutical ingredients and surveys recent developments employing enzymes in organic synthesis Biosynthetic Applications goes over successful drug discoveries and developments by combinatorial biosynthesis and reviews the application of combinatorial biosynthesis among multiple compatible hosts These timely discussions, which cover everything from chemical biology of enzymes, to the redesign of binding and catalytic specificities of enzymes, make this volume a valuable tool for keeping up to date. As such, it is an important read for researchers, students, and professors in the study of biotechnology, life sciences, biochemistry, enzymology, medicinal chemistry, and natural products.
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.
Implementing biocatalytic strategies in an industrial setting at a commercial scale is a challenging task, necessitating a balance between industrial need against economic viability. With invited contributions from small and large-scale chemical and pharmaceutical companies, this book bridges the gap between academia and industry. Contributors discuss current processes, types of biocatalysts and improvements, industrial motivation and key aspects to economically succeed. With its focus on industry related issues, this book will be a useful tool for future research by both practitioners and academics.
The whole range of biocatalysis, from a firm grounding in theoretical concepts to in-depth coverage of practical applications and future perspectives. The book not only covers reactions, products and processes with and from biological catalysts, but also the process of designing and improving such biocatalysts. One unique feature is that the fields of chemistry, biology and bioengineering receive equal attention, thus addressing practitioners and students from all three areas.
This book describes recent progress in enzyme-driven green syntheses of industrially important molecules. The first three introductory chapters overview recent technological advances in enzymes and cell-based transformations, and green chemistry metrics for synthetic efficiency. The remaining chapters are directed to case studies in biotechnological production of pharmaceuticals (small molecules, natural products and biologics), flavors, fragrance and cosmetics, fine chemicals, value-added chemicals from glucose and biomass, and polymeric materials. The book is aimed to facilitate the industrial applications of this powerful and emerging green technology, and catalyze the advancement of the technology itself.
Biocatalysis, that is, the use of biological catalysts (enzymes, cells, etc.) for the preparation of highly valuable compounds is undergoing a great development, being considered an extremely sustainable approach to undertaking environmental demands. In this scenario, this book illustrates the versatility of applied biocatalysis for the preparation of drugs and other bioactive compounds through the presentation of different research articles and reviews, in which several authors describe the most recent developments in this appealing scientific area. By reading the excellent contributions gathered in this book, it is possible to have an updated idea about new advances and possibilities for a new exciting future.
Because enzyme-catalyzed reactions exhibit higher enantioselectivity, regioselectivity, substrate specificity, and stability, they require mild conditions to react while prompting higher reaction efficiency and product yields. Biocatalysis in the Pharmaceutical and Biotechnology Industries examines the use of catalysts to produce fine chemic
