Figure 1From: Influences of 3-hydroxypropionaldehyde and lactate on the production of 1,3-propanediol by Klebsiella pneumoniaeTime course of 1,3-propanediol fed-batch fermentation by KG1. With an initial concentration of glycerol of 40 g/L. Open squares, biomass; closed squares, 1,3-PD; open triangles, glycerol; closed triangles, lactate; closed inverted triangles, 3-hydroxypropionaldehyde (3-HPA).Back to article page
