Abstract
|
|
|
Crude invertase was obtained from the water extracts of Korean ginseng, Panax ginseng C. A. Meyer, by fractionation with 0.8∼1.0 saturation of ammonium sulfate. The properties of the crude invertase were as follows: Crude invertase was stable in the pH range between 5 and 9, and at the temperature below 35℃. Crude invertase showed the
optimum pH at 5.0 and the optimum temperature at 50℃. The activity of the crude invertase was inhibited by Ag^+, Mn^(++), Hg^(++), Zn^(++), and Rb+, while Ca^(++), Cu^(++), and Fe^(3+) demonstrated remarkable increasing effects on the enzyme activity.
