Abstract
A four stage process for the continuous citric acid production with re circulation of the fermentation broth has been created. The process co nsists of the fermentation stage, extraction stage, reextraction stage and the product stage. In the present paper only the results of the f ermentation stage are presented. The fermentations have been carried o ut in a reciprocating-jet-bioreactor with the fungi Aspergillus niger. The influence of the nitrogen concentration in the influent, the age of the fungi and a strong dilution of the biosuspension are discussed in this paper.
