The effects of sugar compounds (riboflavinylglucoside, riboflavinylgalactoside) were compared with those of phosphoras compounds (riboflavin monophosphate, riboflavin diphosphate) of riboflavin upon the growth of riboflavin-less mutant of Aspergillus oryzae. It was found that positive values of difference (%) of growth efficiency (mycelium/sugar consumed) were obtained in presence of flavin glycosides, while negative values were obtained with flavin phosphates. Moreover the mycelium obtained in presence of flavin glycosides was found to contain a larger amount of glycogen and glucan. This seems to suggest that flavinylglycosides accelerates transglycosidation.
