Fig. 4

Bioconversion of glycerol by L. diolivorans. Illustration of glycerol consumption (a) and 3-HPA as well as 3-HP formation (b) during bioconversion of L. diolivorans LMG 19668 + EV (black) and L. diolivorans LMG 19668 + pduF (blue) on 2% glycerol. For a better illustration, levels of 1,3-PDO which are formed in equimolar amounts of 3-HP are not displayed in this figure. The active biomass for these bioconversion experiments was generated during batch cultivations on MRS-medium supplemented with 1,2-PDO
