2株C. guilliermondia和C. flareri时，他们的媒体几乎没有Fe。测定了核黄素。通过分光光度计。当Fe的浓度为0.5 ~ 1 [γ]/100 ml时。在基础培养基中，获得最高的核黄素产量。附加每100 ml中含有10 [gamma] Fe。急剧减少核黄素的合成，但促进酵母生长。丙酮丁醇梭菌合成核黄素的最适铁浓度为1 [γ]/ml。
Cell proliferation and riboflavin synthesis were retarded in 2 strains of C. guilliermondia and one of C. flareri when their media were made practically free of Fe. Riboflavin was detd. by the spectrophotometer. When the conc. of Fe was 0.5-1 [gamma] per 100 ml. in the basal medium, the highest riboflavin yields were obtained. Addn. of 10 [gamma] of Fe per 100 ml. sharply reduced riboflavin synthesis but enhanced yeast growth. The optimum Fe conc. for riboflavin synthesis by Clostridium acetobutylicum was 1 [gamma] per ml.
