Optimizing E. Coli cell growth performance with in-line, real-time OD600 (abs/mm) monitoring during the fermentation process
This study proposes utilizing an inline- variable pathlength spectrophotometer in a recirculation loop during fermentation to monitor and optimize the growth of E. Coli cells in real-time. This provides distinct advantages vs traditional methods due to the constant modification of path lengths to create a slope-based solution that is always within the linear range of the equipment with no buffer correction required. The growth curve is tracked in real-time using the slope (Absorbance/mm) at 600nm to measure cell density and to optimize growth performance of E. Coli cells. This will serve as a proof-of-concept for the optimal cultivation of E. Coli and production of pDNA.
