摘　　要：发表了从葡萄糖到核黄素的整条生物合成途径。根据这条代谢途径和Ｔ３０突变株的发酵条件试验结果，对阿舒假囊酵母合成核黄素的过程中碳基质流量在ＥＭＰ和ＨＭＰ途径中的分配，油和骨胶在核黄素合成中的不同作用，以及丙酮酸的氧化能力等与核黄素过量合成的关系进行了初步的讨论。The whole pathway of the biosynthesis from glucose to riboflavin is presented in this paper. According to the metabolic pathway and the result of conditional experiments of fermentation for mutant T30,initiative discussions have been carried out:about carbon substretes distribution among EMP and HMP pathways in riboflavin biosynthesis operated by Eremothecium ashbyii,the different effects of oils and gelatin on riboflavin biosynthesis in the course of the cultivation and the relationship between the oxygenolysis ability of pyruvic acid and riboflavin overproduction.
