The microbial production of 1,3-propanediol (1,3-PD) from rawglycerol, a byproduct of biodiesel (BD) process, has a great advantage from economical and environmental standpoints. In this study, the production of 1,3-PD was investigated with 5 types glycerol ; pure glycerol, raw glycerol and pretreated raw glycerol from waste vegetable oil-based BD process, and raw glycerol and pretreated raw glycerol from soybean oil-based BD process. Two strains of Klebsiella pneumoniae and 3 stains of Clostridium butyricum were utilized to investigate the effect of raw glycerol (with and without pretreatment) on 1,3-PD production. Klebsiella pneumoniae strains were generally resistant to all types of glycerol and there was no inhibitory effect of raw glycerol on 1,3-PD production. In contrast, the growth and 1,3-PD production of Clostridium butyricum strains was inhibited in the presence of raw glycerol. The production of 1,3-PD and the extent of growth inhibition were different between raw glycerol from waste vegetable oil-based BD and soybean oil-based BD process. When a simple acid treatment of raw glycerol was performed, the inhibition of Clostridium butyricum strains by raw glycerol was reduced up to the level obtained with pure glycerol.
