## Abstract Raw glycerol, the main byβproduct of the bioβdiesel production process, was converted to 1,3βpropanediol by __Clostridium butyricum__ F2b. In batch cultures, 47.1 g dm^β3^ of 1,3βpropanediol were produced. Continuous cultures were conducted at a constant dilution rate (= 0.04 h^β1^) and
The initial steps of glycerol dissimilation and 1,3-propanediol (1,3-PD) formation by Klebsiella pneumoniae anaerobically grown on glycerol were studied by quantifying the in vitro and in vivo activities of enzymes in continuous culture under conditions of steady state and oscillation and during tra
## Abstract Raw glycerol, produced in significant quantities during several industrial processes, could be further considered as a potential substrate for microbial conversions. In the present report, modelling approaches are used in order to quantify the kinetic behavior of microorganisms capable
