Enzymatic Production of L-Tagatose and L-Fructose from L-Sorbose and L-Psicose, Respectively
D-Tagatose 3-epimerase (D-TE) from Pseudomonas sp. ST-24 catalyzes the epimerization of all D- and L-ketohexoses. D-TE immobilized on Chitopearl beads BCW 2510 was used for the production of L-tagatose and L-fructose from L-sorbose and L-psicose, respectively. The production yield was 20% for L-tagatose from L-sorbose and 65% for L-fructose from L-psicose.
