Concluding Remarks 13 References 13 I. Introduction With recent advances in genomic and genetic engineering, interest in the use of biocatalysis for industrial synthetic chemistry is growing rapidly. Likewise, the range of characterized enzymes and the applica- tions of biocatalysts continue to expand (Rich et al., 2002). In particular, biocatalysis is starting to fulfill its promise as a key tool for the produc- tion of optically pure small organic molecules (for the pharmaceutical and agrochemical sector), in part due to the high chemo‐, regio‐, and stereospecificity and selectivity inherent in enzymatic reactions. In addition, the use of microbial (whole‐cell) catalysts containing these enzymes for biocatalytic synthesis is gaining considerable industrial interest. Microbial processes offer possibilities for biocatalysis, which cannot always be met by use of isolated enzymes. The cellular environ- ment protects the protein, which may lead to improved catalyst stability. Furthermore, reactions involving expensive cofactors [e.g., NADH 1 ADVANCES IN APPLIED MICROBIOLOGY, VOLUME 60 0065-2164/06 $35.00 Copyright 2006, Elsevier Inc. All rights reserved.

However, despite the increased interest from chemists in the appli- cation of enzymes and whole‐cell catalysts, it remains the case that the majority of biocatalytic processes implemented in recent years use isolated enzymes. In this chapter, the focus is on microbial conversions with particular emphasis on the
