Summary:

Biocatalysis has become a useful alternative to chemical transformations for the production of a range of compounds with applications in the food, feed, chemical and pharmaceutical industries. However, it is not necessarily an easy task to obtain the desired levels of performance in terms of rate, yield and selectivity of the reaction. One strategy for optimizing biocatalyst performance is to use non-conventional media, such as non-aqueous heterogeneous systems. In this article, we highlight some of the current trends in biocatalysis in such systems, focusing on reverse micelles, supercritical fluids and ionic liquids.
