• Sommario/riassunto: From reviews to the first edtion:""Bornscheuer and Kazlauskas have set out, and succeeded, in producing a definitive manual on hydrolytic enzymes (especially lipases, esterases, and proteases) for organic chemists. This is quite simply the best book of its type and can be unreservedly recommended to organic chemists who have an interest in using hydrolytic enzymes in synthesis."" (Nicholas J. Turner, University of Edinburgh)""The book is an indispensable source of information on the use of hydrolases in organic synthesis. The subject matter is very well set out, and the chapter
