Riboflavinylglucoside producing activity of the dried mycelia of Mucor javanicus was markedly accelerated by employing maltose or soluble starch as carbon source in the shaking culture. The acceleration was observed in the 0.9 ammonium sulfate-saturation fraction of the cell-free extract of mycelia. The mycelial weight was markedly increased by employing maltose or soluble starch as carbon source but not by glucose or sucrose, which was unable to serve as substrate for riboflavinylglucoside forming enzyme of the mold. Maltose and soluble starch, as well as sucrose and glucose, did not so significantly increase the mycelial weight of Rhizopus javanicus having no riboflavinylglucoside producing activity. It was, therefore, suggested that either riboflavinylglucoside or its producing enzyme might stimulate the growth of M. javanicus.
