Abstract:

A new type of ceramic membrane reactor is proposed for the continuous enzymatic synthesis of oligosaccharides using native enzyme. Beta-Galactosidase (EC 3.2.1.23) catalyses the hydrolysis of lactose to the monosaccharides glucose and galactose and also the transgalactosylation reaction to produce galactosyloligosaccharides (GOS). GOS are non-digestible oligosaccharides which are recognized as prebiotics. GOS consist of a number of oligosaccharides with varying ß-glycosidic linkages depending on the enzyme source. In this work, the results for the continuous production of GOS from lactose by means of physically-confined ß- Galactosidase in a novel ceramic membrane reactor system are presented.
