TLDR
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.About:

Fermentation of glycerol to 1,3-propanediol by Klebsiella and Citrobacter strains
TL;DR: Glycerol-fermenting anaerobes were enriched with glycerol at low and high concentrations in order to obtain strains that produce 1,3-propanediol, and Enterobacterial strains of the genera Enterobacter, Klebsiella, and Citrobacter showed similar product patterns except for one group which formed limited amounts of ethanol, but no propanediol.

Multiple product inhibition and growth modeling of clostridium butyricum and klebsiella pneumoniae in glycerol fermentation
TL;DR: The inhibition potentials of products and substrate on the growth of Clostridium butyricum and Klebsiella pneumoniae in the glycerol fermentation are examined from experimental data and with a mathematical model.
Journal ArticleDOI
Glycerol conversion to 1,3-propanediol by newly isolated clostridia
TL;DR: The observations point to a substantial transfer of reducing potential from ferredoxin to NAD, which finally results in increased 1,3-propanediol production.
Journal ArticleDOI
Pathway analysis of glycerol fermentation by Klebsiella pneumoniae: Regulation of reducing equivalent balance and product formation
TL;DR: Findings indicate the existence of enzymes in K. pneumoniae that transfer reducing equivalents from NADH2 to H2 and 1,3-propanediol flexibility, and the physiological meanings of these regulatory mechanisms are discussed from the viewpoint of bioenergetics and product inhibition.

Fermentative production of 1,3-propanediol from glycerol by Clostridium butyricum up to a scale of 2m 3
TL;DR: The conversion of glycerol to 1,3-propanediol (PD) by Clostridium butyricum DSM 5431 was studied in anaerobic culture and growth and product formation were optimal at pH = 7.0 and T = 35° C, while aeration rate and stirrer speed were found to have no significant influence.
