This research objective prospected to produce rare disaccharide and oligosaccharides by biotechnological methods. First, the material, D-allose was produced from starch by ethanol method. Although we tried to produce D-allose 1-phosphate via D-allose 6-phosphate, the efficiency was quite low. Therefore, we tried to produce this from glucose 1-phosphate using glucoside 3-dehydrogenase newly isolated by ourselves. We also investigate the oxidation of cellobiose using this microbe. As a result, we succeeded to oxidize cellobiose to ketocellobiose. By following reduction of sodium borohydride, we also succeeded to produce objective alosyl-allose at higher efficiency.
