A batch culture system for the production of citric acid by Aspergillus niger TISTR 3089 was studied to determine the effect of aeration and mixing on the volumetric oxygen transfer coefficient (kLa) and power requirement. A 2-l batch stirred-tank was used with impeller speeds of500-900 -rpm at an...
