Abstract EN
1,3-Propanediol (1,3-PD) is an important chemical product which can be used to produce polyesters, polyether, and polyurethanes.
In the process of conversion of glycerol to 1,3-PD by Clostridium large number of byproducts (butyric, acetic and lactic acid) are generated in the fermentation medium.
The aim of this work was to isolate bacteria strains capable of the utilization of these byproducts.
Screening of 30 bacterial strains was performed using organic acids as carbon source.
Selected isolates were taxonomically characterized and identified as Alcaligenes faecalis and Bacillus licheniformis.
The most active strains, Alcaligenes faecalis JP1 and Bacillus licheniformis JP19, were able to utilize organic acids almost totally.
Finally, it was find out that by the use of coculture (C.
butyricum DSP1 and A.
faecalis JP1) increased volumetric productivity of 1,3-PD production (1.07 g/L/h) and the yield equal to 0.53 g/g were obtained in bioreactor fermentation.
Moreover, the only by-product present was butyric acid in a concentration below 1 g/L.
