High‐level extracellular expression of inulin fructotransferase in Pichia pastoris for DFA III production

Abstract

IFTase was expressed in a eukaryotic P. pastoris system for the first time and achieved high-level extracellular expression using a high-cell-density fed-batch cultivation strategy. This demonstrated that P. pastoris was a good candidate for potential DFA III production as a novel IFTase expression system.
