In this process, the elution of adsorbed isoamylase was significantly affected by elution design. When the raw starch‐enzyme suspension was packed into a funnel‐type glass filter instead of being stirred in a flask to elute the adsorbed isoamylase, the recovery was increased from 53.6% to about 81% and the concentration of isoamylase was also increased 42‐fold in the eluted solution. The addition of 1% potassium sorbate into the eluted enzyme solution gave a retention of more than 80% of the recovered isoamylase activity in a 5‐month storage at 4°C. |
