| Abstract/Summary |
Based on experiments carried out on both synthetic media with saccharose and natural one with beet molasses, the correlations between gases exchange and the activity of Aspergillus niger strain during citric acid fermentation were estimated and used in on-line process control. For a continuous monitoring of biomass growth, the carbon dioxide evolution rate was chosen as a parameter that properly reflects all processes connected with biomass development and cells maintenance. For acidogenic activity control, the estimated volumetric product formation rate was used. The parameters were calculated in real time based on the difference between oxygen uptake and carbon dioxide evolution rates.
