1. From the fact that dehydroascorbic acid metabolism of ascorbic acidadapted bacterium was markedly accerelated by adding a small amount of glucose or ascorbic acid, a reductive process is assumed to be involved in the metabolism of dehydroascorbic acid.2. D-Arabinosone was hardly metabolized by unadapted cells, whereas it was slowly metabolized by adapted cells and it was markedly accerelated by adding a small amount of ascorbic acid. It suggests that D-arabinosone is reduced to D-ribose as follows.Ascorbic acid→dehydroascorbic acid -CO2→diketo-L-gulonic acid→L-xylosone→D-arabinosone +2H→D-ribose
