Abstract

The fermentation kinetics of citric acid by Aspergillus niger were studied in a batch system. A simple model was proposed using the logistic equation for growth, the Luedeking-Piret equation for citric acid production and Luedeking-Piret-like equation for glucose consumption. The model appeared to provide a reasonable description for each parameter during the growth phase. The production of citric acid by A. niger is growth-associated.
