Relationship between culture redox potential and culture fluorescence inCorynebacterium glutamicum

Summary

Transient experiments were performed during a batch fermentation ofCorynebacterium glutamicum ATCC 14296 in which the flow of air to the reactor was cut off. The fluorescence of the culture was observed to vary linearly with the culture redox potential during the transient. This observation was made below the sensitivity limit of a dissolved oxygen probe. It appears that redox potential in conjunction with fluorescence measurements are of utility in studying extra- and intracellular reduction states, particularly in the microaerobic regime.
