Biotechnological processes often require the use of immobilized biocatalysts. This translation of the most successful German edition introduces the theoretical background of this rapidly growing field followed by a detailed description of the various techniques of immobilizing, characterizing, and using biocatalysts. The comprehensive discussion of possible applications in industrial processes and in basic research results in a practical guide for everyone involved in these techniques. Furthermore, some selected experiments are added in order to facilitate the understanding of the theoretical...

A large number of comprehensive publications has been devoted to the Antarctic, to its plant and animal life. It is therefore relatively easy to familiarize oneself with the current state of Antarctic research. Nothing comparable is available for the Arctic. The heterogeneity and richness of the northern polar regions seem to have discouraged any attempt at a synthethic approach. This book has evolved from an attempt to summarize the results of 15 years of ecological and physiological research work in the Arctic - mostly on Spitsbergen. The necessity of comparing our results and the...
