Abstract: | Continuous production of isomalto-oligosaccharides from maltose syrup by the permeabilized cells ofAureobasidium pullulans immobilized into calcium alginate gel was studied using a column reactor. The immobilized cell column maintained its full activity over 45 days when the reactor was operated at a velocity of 0.1 h–1 at 50°C using 60%(w/v) maltose syrup as a substrate, and the maximum productivity achieved was around 60 g/1h. |
