Abstract/OtherAbstract:
|
Acetobacter xylinum for bacterial cellulose production was cultivated in a modified airlift reactor. Better results were obtained from the modified reactor than from a conventional bubble column. After 72 h of cultivation, the final concentration of bacterial cellulose was 7.72 g/l and the productivity was 0.107 g/l per h in the modified airlift reactor. The concentration of bacterial cellulose was about three times higher than that produced in the conventional bubble column. Moreover, the bacterial cellulose produced using the modified reactor formed a unique elliptical pellet (the average diameter was 10 mm), which is different from the fibrous form produced using the stirred-tank reactor. The modified airlift reactor with the suspended bacterial cellulose in pellet form had a higher volumetric oxygen-transfer coefficient and mixing capability than that with bacterial cellulose in fibrous form. The dissolved oxygen in the modified airlift reactor could be maintained above 35% throughout the cultivation. |
