摘　　要：淀粉水解液中约30%的葡萄糖异构成果糖作碳源进行短梗霉多糖发酵,转化率与蔗糖作碳源相似,这是短梗霉多糖发酵中一条提高淀粉利用率的途径。Utilized Sucrose as carbon source for fermentation production of pullulan, the yield were 60%. But when Starch-hydrolyzate as an alternative of sucrose as carbon source, the yield were less than 45%. utilize some carbon sources containing fructose, the yield tend upwards. We utilized isostarch-hydrolyzate as only carbon source and got an yield as similar as that sucrose did.
