Title: Isolation,identification and fermentation characterization of a 1,3-propanediol product bacterial
Abstract: A bacterial strain named as 2-1 was isolated from activated sludge,which can product 1,3-propanediol(1,3-PD) from glycerol.Morphologic properties,physiological and biochemical char-acteristics and 16S rRNA gene sequence analyses were used to identify the strain.The phylogenetic analysis of the 16S rRNA sequence indicated that the strain 2-1 closely with Klebsiella pneumoniae(CP001891),whereas,the homologous rate was 95.4%.The strain 2-1 might represent a new species.In the fed-batch fermentation at 5 L fermentor:the maximum concentration of 1,3-PD was 63.5 g/L;pro-ductivity was 2.19 g/(L·h);substrate conversion rate was 0.64 mol/mol.
