Automated control system for submerse fermentation of citric acid.Peer-reviewed article

J. KOČAN, L. BOHÁČIK, S. KRČMÁŘ

The technology of the citric acid production by Aspergillus niger changes from the surface growth procedure to the submerse one at present. The submerse procedure was analyzed by the help of a mathematical model. The procedure was simulated by the model using experimental results with the aim to optimalize the inflow of nitrogen source into the medium. At the end the informative description of the on-line controlled fermentation with the computer system DASOR 601 is made. The application of this system on the production fermenter of 150 m³ is in preparation in Research Institute of LIKO at present.
