ABSTRACT
This study investigates potential limitations of 1,3-propanediol formation by Lactobacillus diolivorans. Particular focus is given to enhanced glycerol utilization as well as the elimination of by-product formation. The key aspect is a modulation of the redox household by process engineering through the application of carbon pulses. A shift in the product pattern of C3 products was achieved, improving the ratio of 1,3-propanediol versus 3-hydroxypropionic acid up to a level of 201. Moreover, in combination with alternative feeding strategies this ratio was enhanced up to 451 and the maximum observed productivity of 1,3-propanediol could be significantly increased to 1.7g/Lh.
