Abstract
The fermentation conditions of dextran using corn steep liquor(CSL)and peptone as mixed nitrogen source were studied in this paper.The optimal fermentation conditions were obtained as followed:the concentration of CSL and peptone were 0.08% and 0.1% in seed medium,respective- ly.The concentration of CSL and peptone were 0.1% and 0.08% in fermentation medium,respectively.By applying these optimum conditions,the yield of dextran product reached 91.8% and the activities of cells were high.
