COMPARATIVE STUDIES OF THE METABOLISM OF RIBOFLAVIN OF ORDER MUCOFALES : (I) FORMATIONS OF RIBOFLAVINYLGLUCOSIDE WITH MUCOR AND OF A NEW RIBOFLAVIN DIPHOSPHATE WITH RHIZOPUS

Abstract

It was found that riboflavinylglucoside and some riboflavinyloligosaccharides were formed by Mucor javanicus, M. racemosus and M. rouxianus. A new riboflavin diphosphate was discovered using Rhizopus javanicus. It was suggested that the comparative biochemistry of Mucor and Rhizopus might be useful for the investigation of the biological significances of these glycosides and phosphates of riboflavin.
