The conditions under which Klebsiella pneumoniae batch fermentation glycerol produced 1,3-propanediol(PDO) were optimized in this study;thereby the best fermentation conditions for the STR-50L and the ATR-15L were determined and the ultimate consistency and productivity rates of PDO and the molar yield of PDO from glycerol were 80.97 g/L,1.69 g/(h·L),0.57 mol/mol,74.81 g/L,1.56 g/(h·L) and 0.50 mol/mol,respectively.In comparison with the latter,the concentration of PDO and glycerol mole conversion of the former was increased by 8.23% and 14.91%,respectively.Furthermore,the most appropriate substrate concentration was approximately 25g /L(in the initial glycerol concentration of total).
