Journal ArticleDOI
Microbial production of 1,3-propanediol.
TL;DR: Great efforts are now being made to combine the pathway from glucose to glycerol successfully with the bacterial route from Glycerol to 1,3-PD, which may become the first bulk chemical produced by a genetically engineered microorganism.
Journal ArticleDOI
High concentration and productivity of 1,3-propanediol from continuous fermentation of glycerol by Klebsiella pneumoniae
TL;DR: In a continuous fermentation of glycerol by Klebsiella pneumoniae, a final propanediol concentration of 35.2–48.5 g l−1 and a volumetric productivity of 4.9-fold higher can be obtained at dilution rates between 0.1 and 0.25 h−1, correspond to about 80–96% of the theoretical maxima under ideal conditions.
Journal ArticleDOI
Fermentation of glycerol to 1,3-propanediol and 2,3-butanediol by Klebsiella pneumoniae
TL;DR: At any of the pH values tested, excess glycerol in the culture enhanced the butanediol yield, and the undissociated acid being a stronger trigger than the less toxic diols and acid anions.
Journal ArticleDOI
Kinetic, dynamic, and pathway studies of glycerol metabolism by Klebsiella pneumoniae in anaerobic continuous culture: III. Enzymes and fluxes of glycerol dissimilation and 1,3-propanediol formation.
TL;DR: Results from oscillating cultures revealed that both in vitro and in vivo activities of the enzymes oscillated, and the average values of the in vitro activities during an oscillation cycle agreed well with their corresponding values for nonoscillating cultures under similar environmental conditions.
Journal ArticleDOI
Enzymatic evidence for an involvement of pyruvate dehydrogenase in the anaerobic glycerol metabolism of Klebsiella pneumoniae
TL;DR: In this work, enzymatic evidence is presented that confirmed a simultaneous involvement of pyruvate dehydrogenase complex (PDH) and excluded the presence of pyRuvate:ferredoxin oxidoreductase in this anaerobic bioprocess.
