Replacing the very successful loose-leaf format, this invaluable set of protocols covers those areas where cells and enzymes have been proven to be useful catalysts.From 1992-1997 Preparative Biotransformations was published in the loose-leaf format. During this time 800 pages of detailed protocols on the use and handling of cells and enzymes in organic synthesis were collected. This collection of protocopls has become very valuable and useful. Today's chemists are expected to be able to use enzymes as normal catalysts. In this key reference source, anyone working in area of synthesis will find the necessary techniques and skills to master the problems of using these 'non-chemical' catalysts. It includes:* A collection of procedures originally published in the looseleaf publication, 'Preparative Biotransformations'* Includes a state-of-the-art review by Professor S.M. Roberts not previously published* Contains fully tested and validated protocols* Step-by-step instructions for the expert and the inexperienced chemist
