Abstract 

In batch cultures of Brevibacterium ketoglutamicum for the L-omithine production in which the pH and dissolved oxygen concentration were regulated constant, the profiles of redox potential were observed in parallel with the profiles of state variables such as cell, glucose, and omithine concentrations. It was found that the redox potential had a close relationship with cell concentration and was also affected by omithine concentration. The effects of omithine and glucose on redox potential were examined in a separate series of experiments. Based on the experimental results, a correlation of redox potential to glucose, cell and omithine concentrations has been proposed. The proposed correlation can be used for on-line estimation of omithine concentration from on-line data of redox potential, glucose concentration, and cell concentration.
