Immobilization of levan fructotransferase for the production of di-fructose anhydride from levan
Levan fructotransferase (LFTase) from Arthrobacter ureafaciens K2032 was immobilized on various carriers of which Chitopearl BCW2501 beads showed the higher activity of 320 U g(-1) for the formation of di-fructose anhydride compounds. The immobilized enzyme retained about 60% of its initial activity after being used for 20 cycles.
