✦ Synopsis

ty, efficiency and operational stability. The immobilization mechanism was investigated and the reaction conditions for leucrose formation were optimized. A surprising aspect was the finding, that yields and selectivity were much improved by reactions in ice. Referring to technical application of leucrose formation, the productivity of a continuous process proved to be optimal in a tubular reactor; it compares favorably with a discontinuous use of the immobilized enzyme.

Dextransucrase catalyses the formation of dextran, but also of numerous oligosaccharides from sucrose and different acceptors, if appropriate conditions are chosen. Much experimental work has been carried out and a scheme of reactions and a mathematical model have been developed to describe the comp
