Influence of dissolved oxygen concentration and shear rate on the production of pullulan by aureobasidium pullulans

Experiments were carried out with Aureobasidium pullulans (ATCC 9348) at constant dissolved oxygen concentration (DO = 100 and 50% related to air saturation at 1 bar) and at constant stirrer speeds (n = 500 and 150 (min super(-1))). The higher pullulan yield was achieved at decreased constant DO in...

Beschreibung
Zusammenfassung:	Experiments were carried out with Aureobasidium pullulans (ATCC 9348) at constant dissolved oxygen concentration (DO = 100 and 50% related to air saturation at 1 bar) and at constant stirrer speeds (n = 500 and 150 (min super(-1))). The higher pullulan yield was achieved at decreased constant DO in connection with decreased shear rate. Biomass production was not affected.
