Modern Biocatalysis: Stereoselective and Environmentally Friendly Reactions

Description

This reference covers the wide and rapidly growing field of biocatalysis. It combines complementary expertise from such areas as microbiology, enzymology, molecular biology structural biology and organic chemistry, thus highlighting the interdisciplinary nature of the subject.

With its special focus on progress and new developments towards environmentally beneficial reactions with high levels of selectivity for the production of key compound classes, this book will enlighten both chemists and biologists as to the advances and opportunities existing in enzyme catalysis.

Editorial Review

Biocatalysis is fascinating field that continues to evolve, occasionally producing surprises such as biocatalyzed Baeyer-Villiger reactions. To give an overview of all enzyme-catalyzed reactions would definitely be the wrong way to go, since such a systematic collection presumably could not be rendered in a usable format. Therefore, the editors of this monograph have taken the right approach in limiting themselves to important and particularly interesting enzyme-catalyzed reactions, and moreover to focus on industrial applications, for example, such as employing alternative solvents or the use of microreactors.

The make-up of the chapters is a bit surprising and very unsystematic, so that there are chapters with basic techniques such as fluorescence assays for screening enzyme libraries and immobilization mixed together with specific applications. With the scope and depth of the texts, however, the reader will happy discover that the majority of the authors made a significant effort with the introductions and the number of examples, whereas three of the chapters rather limit themselves more to a brief overview. A few of the later portions certainly appear to be quite specific, making the book appear more as a collection of good review articles that can be read through when the need arises, rather than as a textbook to be worked through linearly. It is quite otherwise for the initial chapters, however, which explain fundamental techniques and are absolutely worth reading.

The book is thus to be recommended to anyone who is interested in strengthening their knowledge of enzyme-catalyzed reactions, and specializing in industrial applications. Researchers who do scale-up work in industry will find some interesting techniques and important reactions described, so that getting hold of this book will be worthwhile..
