Peak OD 600 reached 93.4 to 95.8 in XDR-200 MO fermentor, which means that it can support high OD 600 E. coli growth. Scale up from the 5 L fermentor to 80 and 160 L gave comparable peak OD 600, plasmid titer, and SC percentage, which means you can rely on XDR-200 MO fermentor for good E. coli growth and plasmid production.
