Abstract

Dextranase, isolated from Penicillium funiculosum and P. lilacinum, was immobilized on porous, silanized-silica beads and a phenol-formaldehyde resin. A commercial dextran of relatively low molecular weight (∼2 × 10 6) was degraded by immobilized dextranase, with the formation of reducing sugars, but with little decrease in viscosity. In contrast, soluble dextranase caused rapid loss of viscosity, but only a slight increase in reducing sugar. Native dextran of high molecular weight, from Leuconostoc mesenteroides NRRL B-512 (F), was attacked very slowly by immobilized dextranase, with the release of oligosaccharides of low molecular weight.
