Studies on the Conditions of Fermentation of Pullulan by Aureobasidium pullulans
短梗霉多糖发酵条件的研究

The studies on suitable conditions for pullulan fermentation according to the results obtained from the shaking flask tests was carried out in 16L auto-controlling fer-mentor. It fount that the optimal DE value of starch hydrolyzate was 40-50 when 10% starch was used as carbon source. The optimal concentration of ammonium sulfate in the medium for fermentor was different from that of the shaking flask. The fermentation kinetics and effects of seed age, seed volume, airflow rate, pressure of tank, agitation speed and number of vane group on the production of pullulan were investigated.
