Abstract: In this paper,the property of β-Fructofuranosidase from Arthrobacter sp. was studied. The best temperature for getting total activity was 35℃,and pH was 6.5. The optimun condition for getting high percent lactosucrose was that temperature was 42℃ and pH7.0.This enzyme can use sucrose and lactose as raw materials for synthesizing Lactosucrose.

Key words: Arthrobacter sp β-Fructofuranosidase , Property , Lactosucrose
