%X After comparing the varieties of parameters in batch culture under different dissolved oxygen tension by Bacillus pumilus, we found that the demand of cell on oxygen in different phase isn' t consistent. Based on the analys is of the metabolic pathway of oxygen and the mechanism of the effect of dissolved oxygen tension on fermentation of D-ribose, a two-stage oxygen-supply control mode was proposed and experimentally proved to be available. High ribose yield and high glucose consumption rate were achieved during whole process for 44h, and the ultimate ribose concentration and cell concentration were 5.0% and 18.8% higher than former respectively.
