Fig. 6From: Development of a plasmid stabilization system in Vibrio natriegens for the high production of 1,3-propanediol and 3-hydroxypropionateProduction of 3-HP by strain VN14 and strain VN15 (with a plasmid maintenance system) during fed-batch fermentation. A Fermentation profiles of strain VN14; B Plasmid maintenance ratio by strain VN14; C Activity of aldehyde dehydrogenase of strain VN14; D Fermentation profiles of strain VN15; E Plasmid maintenance ratio by strain VN15; F Activity of aldehyde dehydrogenase of strain VN15. 100 mg/L of ampicillin was added during the fermentation of strain VN14, while no antibiotics were added during the fermentation of strain VN15Back to article page
