Comparison of Two Natural 1,3-Propanediol Producers in Regards to the Effect of Glucose Usage as a Co-substrate

WOS: 000358302100011Biodiesel production, in which glycerol is produced as a by-product, has increased significantly and now vast amounts of glycerol have been considered as a waste product. Biotechnological conversion of glycerol into a valuable bioplastic raw material, namely, 1,3-propanediol (1,3-PDO) seems to be very promising. In this study, locally isolated Klebsiella pneumoniae and Clostridium beijerinckii NRRL B593 were comparatively studied for their 1,3-PDO production potential with the addition of different concentrations of glucose together with glycerol. Addition of a co-substrate enhanced the molar yields of 1,3-PDO by 11% only for K. pneumoniae with an addition of 1 g/L of glucose.TUBITAK-CAYDAGTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [109Y150]; EBILTEMEge University [2008BIL032]The authors gratefully acknowledge TUBITAK-CAYDAG (Grant No. 109Y150) and EBILTEM (Grant No. 2008BIL032) for the support.
