Abstract
Problem: To provide a microorganism with an ability to produce deoxy polyol dehydrogenase.Means for Resolution: A microorganism belonging to genus Enterobacter with an ability to produce a dehydrogenase for deoxy polyol of the same structure at the positions C2 and C3 as that of ribitol or L-iditol. The bacterial cell IK7 of the genus Enterobacter (accession No. NITE P-271). A method for producing deoxy ketose comprising allowing a culture containing the deoxy polyol dehydrogenase obtained by the culturing of the microorganism of the invention or allowing the deoxy polyol dehydrogenase to react with a solution containing deoxy polyol of the same structure at the positions C2 and C3 as that of ribitol or L-iditol to oxidize deoxy polyol to produce the corresponding deoxy ketose and then collecting the deoxy ketose. The deoxy polyol is 1-deoxy-D-allitol, while the corresponding deoxy ketose is 1-deoxy-L-psicose. Otherwise, the deoxy polyol is L-rhamnitol, while the corresponding deoxy ketose is 1-deoxy-L-fructose.
