The completely revised second edition of this user-friendly and application-oriented overview of one-step biotransformations of industrial importance. Based on extensive literature and patent research, this book is unique in arranging each process in a systematic way to allow for easy comparison. All the chapters have been rewritten, with all the processes updated and more than 30 new processes added. Each set of data is accompanied by key literature citations, supported by flow sheets where available, reduced to their significant elements. In addition, an extensive index classified by substrates, products, enzymes, and companies provides direct access to each process, organized according to enzyme class. Biotechnologists, biochemists, microbiologists, process engineers and those working in the chemical and biotechnological industries will find here all the significant parameters characterizing both the biotransformation and the process.

Industrial Biotransformations - a user-friendly and application-oriented up-to-date overview of one-step biotransformations of industrial importance. The data conferring each process is arranged in a convenient format to survey so that the processes can easily be compared. Each set of data is accompanied by key literature citations. As far as flow sheets of the processes are available, these are given reduced to their significant elements. An extensive index classified by substrates, products, enzymes, and companies provides direct access to each process organized in the order of enzyme classes. The reader will find all significant parameters characterizing the biotransformation itself and the process.

The use of natural catalysts - enzymes - for the transformation of non-natural is not at all new: they have been used for more man-made organic compounds than one hundred years, employed either as whole cells, cell organelles or isolated enzymes [1]. Certainly, the object of most of the early research was totally different from that of the present day. Thus the elucidation of biochemical pathways and enzyme mechanisms was in the foreground of the reasearch some decades ago. It was mainly during the 1980s that the enormous potential of applying natural catalysts to transform non-natural organic compounds was recognized. What started as a trend in the late 1970s could almost be called a fashion in synthetic organic chemistry in the 1990s. Although the early euphoria during the 'gold rush' in this field seems to have eased somewhat, there is still no limit to be seen for the future development of such methods. As a result of this extensive, recent research, there have been an estimated 5000 papers published on the subject [2]. To collate these data as a kind of 'super-review' would clearly be an impossible task and, furthermore, such a hypothetical book would be unpalatable for the non-expert.

This volume provides a clear understanding of how microbes, following their degradative processes, contribute maximally to the benefit of mankind through biotransformations of waste materials as well as a wide variety of health-risk compounds. The book contains twenty four chapters contributed by leading scientists from different parts of the world, covering various aspects of bioremediation of xenobiotics such as toxic, carcinogenic, teratogenic, and mutagenic compounds, which include halogenated aromatics, derivatives of heavy metals, microbial toxins, tannins, dyes, sulfur compounds of coal and petroleum and pesticides. The bioremediation of agricultural residue, industrial as well as municipal wastes, fuel oils, lubricants, natural rubber products, and other synthetic polymers, which pollute the environment substantially, also constitutes an important component of the book. All biotechnological aspects of microbial transformations pertaining to biodegradation/bioremediation of hazardous wastes, ranging from screening methods for microbes with degradative potential, processes of degradation, strain improvement for enhanced biodegradation and elimination of xenobiotics of health and environmental concern have been dealt with. The book intends to widen the scope of Applied Microbiology and Biotechnology in general and biotransformations in particular. It will provide an opportunity for scientists in the areas of biochemistry, food industry, environmental science and engineering and their implications in technologically feasible, environment friendly and economically viable bioremediation options. Also, it forms an interface between agro-industrial establishments and the academic world and will generate new thought provoking ideas for scientists of future generations for the safeguard of both human and animal health as well as the environment.

This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts—principles of stereoselective transformations, enzyme properties and kinetics—the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C–C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques, artificial enzymes and the design of cascade-reactions are treated in a separate section. A final chapter deals with the basic rules for the safe and practical handling of biocatalysts. The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale. In this 7th edition new topics have been introduced which include alcohol and amine oxidases, amine dehydrogenases, imine reductases, haloalkane dehalogenases, ATP-independent phosphorylation, Michael-additions and cascade reactions. This new edition also emphasizes the use of enzymes in industrial biotransformations with practical examples.

From the laboratory to full-scale commercial production, this reference provides a clear and in-depth analysis of bioreactor design and operation and encompasses critical aspects of the biocatalytic manufacturing process. It clarifies principles in reaction and biochemical engineering, synthetic and biotransformation chemistry, and biocell and enzy

Biocatalysts are increasingly used by chemists engaged in fine chemical synthesis within both industry and academia. Today, there exists a huge choice of high-tech enzymes and whole cell biocatalysts, which add enormously to the repertoire of synthetic possibilities. Practical Methods for Biocatalysis and Biotransformations 2 is a "how-to" guide that focuses on the practical applications of enzymes and strains of microorganisms that are readily obtained or derived from culture collections. The sources of starting materials and reagents, hints, tips and safety advice (where appropriate) are given to ensure, as far as possible, that the procedures are reproducible. Comparisons to alternative methodology are given and relevant references to the primary literature are cited. This second volume – which can be used on its own or in combination with the first volume - concentrates on new applications and new enzyme families reported since the first volume. Contents include: introduction to recent developments and future needs in biocatalysts and synthetic biology in industry reductive amination enoate reductases for reduction of electron deficient alkenes industrial carbonyl reduction regio- and stereo- selective hydroxylation oxidation of alcohols selective oxidation industrial hydrolases and related enzymes transferases for alkylation, glycosylation and phosphorylation C-C bond formation and decarboxylation halogenation/dehalogenation/heteroatom oxidation tandem and sequential multi-enzymatic syntheses Practical Methods for Biocatalysis and Biotransformations 2 is an essential collection of biocatalytic methods for chemical synthesis which will find a place on the bookshelves of synthetic organic chemists, pharmaceutical chemists, and process R&D chemists in industry and academia.
