| Summary |
In recent years, enzymatic catalysis in organic solvents-as opposed to aqueous solutions-has gained considerable attention as a powerful new approach to the preparation of natural products, pharmaceuticals, fine chemicals, and food ingredients. In Enzymes in Nonaqueous Solvents: Methods and Protocols, leading chemists, biochemists, biotechnologists, and process engineers summarize for the first time a wide range of methods for executing enzymatic transformations under nonaqueous conditions. Each method includes detailed step-by-step instructions for its successful completion, a list of materials, and ancillary notes that explain the scientific basis of the procedure, as well as troubleshooting. Also provided are a generic description of key reactions, advice on biocatalyst preparation, discussion of reaction conditions, and instructions on bioreactor design. Comprehensive and state-of-the-art, Enzymes in Nonaqueous Solvents: Methods and Protocols offers today's synthetic chemists, biochemists, and process engineers all the essential information needed to carry out enzymatic reactions in nonaqueous media, as well as to successfully scale up to production quantities |
