The use of natural catalysts - enzymes - for the transformation of non-natural man-made organic compounds is not at all new: they have been used for more 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 the main reason for research 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 all estimated 8000 papers published on the subject [2-14]. 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.

The use of biocatalysts offers a remarkable arsenal of highly selective transformations for modern preparative organic chemistry. This book provides a basis for biocatalysts and a condensed introduction to the field. After a basic introduction into the use of biocatalysts, the principles of stereoselective transformations, kinetics, and enzyme handling are discussed, and the different types of reactions are explained according to the "reaction principle". This fourth edition includes new chapters on peroxidase reactions and on the handling of biocatalysts.

After a basic introduction spanning the principles of stereoselective transformations, kinetics and enzyme properties, the different types of reactions are explained. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and the use of modified enzymes, are also treated. This new edition features an improved didactic style and includes new developments, such as dynamic resolution, stereo-inversion and enantio-convergent processes.

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 3 will be a companion book to Practical Methods for Biocatalysis and Biotransformations (2009) and Practical Methods for Biocatalysis and Biotransformations 2 (2012). Following the successful format of the two volumes, it will be a “how-to” guide focusing on commercially available enzymes and strains of microorganisms that are readily obtained from culture collections. The source of starting materials and reagents, hints, tips and safety advice (where appropriate) will be given to ensure, as far as possible, that the procedures are reproducible. Comparisons to alternative methodology will be given and relevant references to the primary literature will be cited. Contents include: Biotransformation Process Technology Industrial Biooxidation Hydrolase catalysed hydrolysis/synthesis Reduction Oxidation Halogenation Transferase catalysed glycosylation, methylation, etc C-C bond formation Tandem Biocatalytic Reactions Practical Methods for Biocatalysis and Biotransformations, Volume 3 is an essential collection of validated biocatalytic methods which will find a place on the bookshelves of synthetic organic chemists, pharmaceutical chemists, and process R&D chemists in industry and academia.

Whereas the hydrolases such as proteases, esterases and lipases are sufficiently well researched to be applied in every standard laboratory, other types of enzymes are still waiting to be discovered with respect to their applicability in organic-chemistry transformations on a preparative scale. This latter point is stressed here, with the focus on the newcomer-enzymes'which show great synthetic potential.

The development of new asymmetric catalytic methods is of fundamental importance to industrial synthetic chemistry. The demand for optically pure synthetic intermediates and the drive to adopt greener methods of synthesis have stimulated a growing interest in biocatalysis as a selective and environmentally benign synthetic technique. Practical Biotransformations: A Beginner's Guide provides an introduction to microbes and enzymes and demonstrates their practical applications in synthetic organic chemistry. Designed as a laboratory manual, this user-friendly guide discusses standard laboratory techniques, with appropriate advice on aspects of microbial practice and associated safety. Topics covered include: An introduction to equipment in a biotransformations laboratory An overview of biocatalyst sources Maintenance and growth of biocatalysts Example biotransformations using commercially available microbes and enzymes Basic gene cloning and the use of ‘designer’ biocatalysts This book will be a valuable resource for synthetic organic chemists with little or no experience of biochemistry or microbiology. It is the author’s hope that this text will inspire readers to consider biocatalytic methods as real alternatives to traditional synthetic solutions.
