Abstract

A considerable lowering of aeration demands occurs during diffuse growth of citric acid-producingAspergillus niger in a submerged cultivation. However, the diffuse culture poses stricter demands on the type of aeration and agitation. The impeller frequency affects considerably the morphology of the producer fungus and the accumulation of citric acid. The effect of impeller frequency on the distribution of air in the medium and on the amount of air fed into the diffuse culture is less important.
