IV A microorganism having enhanced levan fructotransferase productivity and a method of producing difructose anhydride IV using the microorganism

摘要

The present invention relates to a nucleic acid-containing Levan fructitin-transferase-secretion expression cassette encoding a levan fructotransferase-encoding nucleic acid and a translational fusion partner (TFP), a vector containing the cassette, A recombinant microorganism containing the recombinant microorganism, and a process for producing a levansucrose transferase and a difructose anhydride IV using the recombinant microorganism.The recombinant microorganism of the present invention can secrete and express the recombinant levan fructosyltransferase at a good efficiency by using a protein secretion fusion factor and can be obtained by reacting the levan fructosyltransferase produced from the microorganism with levan, Can be fermented in a medium containing Levan to effectively produce Diprutosteranhydride IV.
