These proceedings contain most of the oral presentations and posters of the international symposium on Stability and Stabilization of Enzymes held in Maastricht in November 1992. They provide a comprehensive overview of the state-of-the-art in this field.The possible applications of enzymes are enormous. Years of development have seen many enzymes brought onto the market, but they are still expensive to use. Therefore, their efficient application is a prerequisite for common usage. One of the main factors for this efficiency is the stability of the enzymes. The topics thus ranged from the extensive fundamental thermodynamic knowledge gathered in academic research to the practical applied knowledge built up in industry during the time that enzymes have been produced commercially.The subject Stability and Stabilization of Enzymes was discussed from various points of view, as was reflected in the themes of the symposium sessions. In the session on Fundamentals of Enzyme Stabilisation the thermodynamic background of the phenomenon was highlighted. In yet another session, the recently developed analytical tools to measure enzyme stability and stabilisation were discussed. Further sessions comprised the physical, chemical and biological ways to obtain enzyme stabilisation and finally, the industrial practice of enzyme stabilisation was treated by representatives of the world''s most important enzyme producers. The book will be of interest to researchers in universities and industry in the fields of biochemistry, enzymology and biotechnology.

This book contains an introduction to the text of and a commentary on the fragments of two plays by Euripides, the Kresphontes (ca. 424 B.C.) and the Archelaos (ca. 408/7 B.C.)Fragments of both plays are preserved in quotations by other writers and in recently published papyri. The introduction discusses aspects of the background and of the contents of the plays, such as, for example, their first performances, the relation of the Kresphontes with the plays about Orestes, and Euripides' motives in writing the Archelaos (politics or flattery?). The commentary to each play deals with the interpretation of the fragments and testimonia, with textual problems and with typical elements of Euripides' style. This is the first full-scale treatment of both plays and offers, thanks to modern papyrus finds, some new evidence on their composition and context. The text of the papyrus fragments is based on personal inspection of the papyri concerned, which has resulted in a number of new readings.
