TLDR
1,3-Propanediol was produced by Klebsiella pneumoniae using crude glycerol obtained from biodiesel production and it could be concluded that the crude Glycerol could be directly converted to 1, 3-PD without any prior purificationAbstract:
1,3-Propanediol (1,3-PD) was produced by Klebsiella pneumoniae using crude glycerol obtained from biodiesel production. The 1,3-PD concentration of 51.3 g/l−1 on crude glycerol from alkali-catalyzed methanolysis of soybean oil was comparable to that of 53 g/l−1 on crude glycerol derived from a lipase-catalyzed process. The productivities of 1.7 g l−1 h−1 on crude glycerol were comparable to that of 2 g l−1 h−1 on pure glycerol. It could be concluded that the crude glycerol could be directly converted to 1,3-PD without any prior purification.read more

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.

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.
