Verfahren zur Herstellung von L-Ketohexose

摘要

L-Ketohexoses such as L-fructose and L-tagatose are produced from L-psicose and L-sorbose as substrates by allowing D-ketohexose 3-epimerase to act on these substrates. The yield and the production cost of the produced L-fructose and L-tagatose are industrially acceptable. The enzyme is preparable from microorganisms, e.g. those of the genus Pseudomonas.
