Figure 2From: Influences of 3-hydroxypropionaldehyde and lactate on the production of 1,3-propanediol by Klebsiella pneumoniaeTime course of end-products by KG1 and KG1Δldh with different initial concentrations of glycerol. 3-hydroxypropionaldehyde (3-HPA) (A), lactate (B), and 1,3-PD (C). Closed squares, KG1 with 40 g glycerol/L; closed triangles, KG1 with 30 g glycerol/L; closed circles, KG1∆ldh with 40 g glycerol/L. The datapoints represent the mean values and standard deviations of three parallel experiments.Back to article page
