Water-insoluble yeast invertase was prepared by binding native invertase to DEAE-cellulose. Some characteristics of the bound invertase and the continuous hydrolysis of sucrose by use of it are described. The activity of bound invertase corresponded to about 1/2 at pH 3.4 when compared with the maximum activity of free form and it could hydrolyze sucrose into invert sugar perfectly. The apparent optimum pH of bound invertase was shifted toward acid pH by about 2 pH units in comparison with free invertase. Stability of bound invertase to temperature was slightly less in comparison with free invertase at pH 5.2. The continuous sucrose hydrolysis was carried out using bound invertase at pH 3.6 and it could be used about ten times until the hydrolysis ratio decreased to the half of the initial.
